Sorry to respond to a closed bug report, but I just pushed a change to
README-IGC which mentions the use of SIGSEGV by MPS.  While there is
more to be said on the topic (users of lldb on non-macOS systems have to
change signal disposition manually, right now; and solaris/sparc gdb
loses the siginfo information when receiving a SIGSEGV, which means MPS
builds on those systems happen to work but cannot be debugged with gdb),
I've tried to keep it short.

Thanks again for the report!

Pip
