  I can't see anything wrong with it, and I tried it and there was
nothing wrong with it. The error must be somewhere else.

  If you are running it in linux, try running it using valgrind (if you
don't have it, install it; it's essential). In other words:

valgrind ./yourprogram

  If will tell you if you have some out-of-bounds access or memory leaks.
