Use a debugger. If using Visual C(++)... pause once it hangs, and look up where it is at that point.

If on Linux or the like, check out gdb (on gnu.org). You''ll want to run the program, pause it, and then run a "backtrace" (command: bt) which lists the function the program is in, and the function it was called from, and the function that called it, and so forth. This will help you track down the problem.
