core dumped every time when my code is finishing

[Zhang, Dongmin]

This is my code. Very simple one. Every time when I run my code, after it
finishes all the work, I use gdb to trace it to "return 0;", after return 0;,
it crashes. I have the same problem to run the example codes. My machine is a
linux box with gcc 3.2.2. I don't know what was wrong.

Thanks a lot.
