Here's mine:

I was working on a Pascal program on a PC, with lots of pointers here
and there.  I was running the program to test some new functions, but
of course it didn't work right the first time.  But at least it exited
cleanly.

Or so I thought.  About an hour later, I was copying some large files
over to diskette, and was puzzled by the speed of copying.  So I
decided to check before I deleted the files on the hard disk.

It turned out that every time I had copied a file for the last hour,
the copy was created with a length of 0 bytes....
