You don't identify the platform or O/S, though I'd guess some Linux
distro on i386 or x86-64...

If you have gdb available, a backtrace might give a clue.

However, as this is a new major release of gcc I'm automatically going to
assume an optimisation issue.  To test this I'd suggest doctoring the
makefile generated by configure to reduce the optimisation level - I'd
suggest trying -O instead of -O3.  If that works, try -O2 or -Os.

If -O2 or -Os works, I'd be taking the matter up with the gcc team.
