Comment (by ryandesign):

 I'm not sure that anybody here can help you with this, especially since
 nobody has volunteered to be the maintainer of the gcc ports. You may need
 to research the issue yourself, possibly with the assistance of the
 developers of gcc, if you want a solution.

 A segmentation fault is a crash. When a crash happens, macOS records a
 crash log in Library/Logs/DiagnosticReports. The contents of that crash
 log may help pinpoint what was happening when the crash occurred.
 Attaching it here may help someone else help you further.
