--- Comment #10 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
Could you backtrace the segfault?

1. Run g++ with added option "-v", and find out the command-line with "cc1plus"
in the output.
2. Then run this "cc1plus" command-line under a debugger, prefixing your
command line with "lldb -- " or "gdb -args "
3. When it segfaults, get a backtrace through debugger command "bt"
