That single line of Fortran simply wasn't working.

After several hours of fruitless debugging, I swallowed my pride and had a buddy step through the code with me.

Most of my stupid bugs haven't been actual bugs. They have been bad data and my assumptions about that data.

I have spent hours trying to find a bug in code where there wasn't one - I was debugging an old piece of code or I assumed that my test data set was something... and it wasn't.

blocks|key|4205418|text|我不确定这是不是最愚蠢的，但我经历过的最糟糕的一次是，我写了一些访问控制例程，这些例程部分依赖于一天中的时间(所以你可以写一些规则，比如“这只能在工作日的办公时间内访问”)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4205419|我已经完成了代码并运行了所有的测试，一切工作正常。然后我回到家，下一个工作日来了，运行了我所有的测试，它们都失败了。既然代码和所有的测试都是完全不变的，我无论如何也想不出为什么会发生这种情况。|4205420|原来夏令时已经生效了，而我的代码不能处理这一点。|4205421|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Not sure if it was the most stupid, but the nastiest one I ever had was where I had written some access control routines that depended in part on time of day (so you could write rules like 'this can only be accessed on a workday during office hours'). 

I had finished the code and ran all my tests and everything worked fine. Then I went home, came in the next work day and ran all my tests and they failed. I couldn't for the life of me figure out why this had happened since the code and all the tests were completely unchanged. 

Turned out that daylight savings time had kicked in, and my code didn't handle that.

blocks|key|142238|text|当我对花括号语言缺乏经验时，我曾经写过这样的东西：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|142239|if+(expr);

When I was much less experienced with curly brace language, I once wrote something along the lines of:

<pre><code>if (expr);
 stmt;
</code></pre>

It was in an embedded system, so my debugger and printf were powerless. It just made the audio sound bad. I put it down to poor performance and spent a day or so optimising it. A back of an envelope calculation would have shown that performance was not a problem.

From that day I always put my braces in. It makes me want to write in Python, if it wasn't for the rest of the language.

blocks|key|938256|text|很久以前，在我高中的CS时代，我用Turbo+Pascal+(我想)实现了一个二叉树。其中一个操作没有正确处理它的指针，最终覆盖了代码段的一部分(啊，DOS编程的乐趣)。无论如何，它总是覆盖我放入的所有调试代码，使IF语句看起来是假的，打印语句不会发生，等等，但所有这些都奇迹般地没有崩溃，并且几乎不可能知道发生了什么。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|938257|最后，我通过汇编级调试器运行它，当指令在函数中间开始更改时，我发现了这个问题……|938258|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Long ago in my high school CS days, I implemented a binary tree in (I think) Turbo Pascal. One of the operations didn't quite handle its pointers correctly and ended up overwriting parts of the code segment (ah, the joys of DOS programming). Anyway, it always ended up overwriting all the debugging code I put in, making IF statements seemingly lie, print statements not happen, and the like, but all miraculously without crashing, and made it pretty much impossible to tell what was going on.

Eventually I ran it through an assembly-level debugger and caught the problem when the instructions started changing in the middle of the function...

blocks|key|141949|text|有一次，当我在做一些与数学编程相关的作业时，我花了几个小时才弄清楚我需要一个*的地方有一个%2B。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|141950|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Once when I was doing some math programming related homework it took me a couple of hours to figure out I had a + somewhere where I needed a *.

blocks|key|933329|text|我正在使用flex/bison编写解析器。一个特性是常量折叠优化，即用22替换20+%2B2，但是我的解析器将其替换为4。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|933330|作为lexer的一部分，我有一个符号表。我使用了一个带有strncpy的线性搜索来搜索现有条目。但是，对于strncpy中的length参数，我对符号表中的字符串使用了strlen。这不是一个聪明的想法，因为如果符号表中的条目比添加的条目小，那么它将不正确地匹配。例如，添加"20“将匹配到"2”，因为只比较第一个字符。因此，当我的解析器查找"20“的符号时，得到的是"2”。我花了几个小时才弄明白为什么我的20岁变成了2岁。|933331|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I was writing a parser using flex/bison. A feature was constant folding optimization, i.e. replacing 20 + 2 with 22, however my parser was replacing it with 4.

As part of the lexer I had a symbol table. I used a linear search with strncpy to search for existing entries. However, for the length parameter in strncpy I used strlen on the string in the symbol table. Not a clever idea, because if the entry in the symbol table is smaller then the one being added it will incorrectly match. For example, adding "20" would match to "2" because only the first character is compared. Therefore when my parser looked up the symbol for "20" it got "2". I took me hours to figure out why my 20s were changing to 2s.

This isn't my bug but I was present for it. My Wife and I took a java class together when we were in college. She's in Anthropology and I'm in finance but somehow we ended up in java. I loved it.

She spent an entire evening trying to make a "damned program draw a stupid $%^&amp;*( house on the screen" and just couldn't. Being stubborn, she resisted any of my assistance until her final moment of desperation (2, 3 am?). I took a quick look and notice she had used "O" (letter o) instead of "0" (zero) throughout.

She withdrew from the class the next day.

Personally, I have a few dumb mistakes that can be common. My favorites are:

dollar sign + function_name
using the same iterate ($i) instead an already looping $i iterate loop
the random "`" that happened SOMEWHERE because my hand slipped

I once was debugging a program that was multithreaded, but where the multithreading could be disabled. The program would segfault randomly, but only with multithreading enabled. After trying to isolate every race condition possible, I realized that the only problem was that I was writing past an array bound. In single-threaded mode, the memory allocator was allocating memory predictably, such that the data at the address directly above this array was not needed anymore by the time it was overwritten, so the bug did not have any symptoms. In multithreaded mode, the data at these addresses was data owned by other threads.

<pre><code>foreach(Column column in Table.Columns)

This is one of my early stupid bug.

We got a existing project to work on, where there is the <code>WebMethod</code> written in C#

<pre><code>switch (option) {
case "one" :
 //ToDos
 break;
case "two" :
 //ToDos
 break;
case "three" :
 //ToDos
 break;
}
</code></pre>

Whereas from clientCode (via ajax) we received the following as <code>option</code>

<pre><code>One
Two
Three
</code></pre>

I couldn't understand where the problem, after around 30 - 40 minutes I got. 

I fixed it like 

<pre><code> switch (option.ToLower()) {
</code></pre>

I was working on a project that missbehaved, for some reasons no exception was thrown even when it should have. Deep down I have found this kind of error handling:

<pre><code>try {
 m.invoke(parentObject, paramObj);
} catch (IllegalArgumentException e) {
 new CaseLibException(e);
} catch (IllegalAccessException e) {
 new CaseLibException(e);
} catch (InvocationTargetException e) {
 new CaseLibException(e);
}
</code></pre>

My brain recognized that several exceptions were wrapped into another one, so that's not so bad. But I had to stumble over this code at least 3 times to see what's missing...

我正在做一个错误行为的项目，由于某些原因，即使在它应该抛出的时候也没有抛出异常。在内心深处，我发现了这种错误处理方式：try {    m.invoke(parentObject, paramObj);} catch (IllegalArgumentException e) {    new CaseLibException(e);} catch (IllegalAccessException e
