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

Answer 1

I haven't heard of anything specific about GCC weirdness under Cygwin but in your case it would probably be a good idea to use the -Wall command-line option to gcc to show all warnings, to see if it finds anything that might be causing the segfault in your code.
