A segmentation fault could be caused a number of different things. If the program has large arrays, try compiling with the option -heap-arrays. This will store arrays in heap memory rather than on the stack which is limited to 2 GB. I would also suggest, turning on runtime checking with -check all to isolate the issue. This will slow down your program considerably though, so do not leave it on in release mode.
