C program compiled with cygwin in Windows works, segmentation fault under Linux. Is cygwin GCC 'bad'?

Question

For my Programming 102 class we are asked to deliver C code that compiles and runs under Linux. I don\'t have enough spare space on my hard drive to install Linux alongside Wind

You definitely have a bug somewhere in your code. It's possible that the Windows memory manager is being more lax than the Linux memory manager. On Windows, you might be doing bad things with memory (like overwriting array bounds, memory leaks, double-free'ing, etc.), but it's letting you get away with it. A famous story related to this can be found at http://www.joelonsoftware.com/articles/APIWar.html (search for "SimCity" on that (somewhat lengthy) article).
