When I was taking a computer graphics course at the University of
North Carolina - Chapel Hill, we switched from Sun's C++ to g++ and
experienced several very annoying bugs.  I can't remember what they all
where, but one was the following:

In a class header file, we declared two variables like so:

...
 image *image1;
 image *image2;
...

If something was assigned to image2, the program seg faulted.  It we then
made the one change:

...
 image *image2;
 image *image1;
...

Then the assignment to image2 worked, but assignments to image1 seg faulted.
