I'm afraid I can't help *much* with the debugging, but on my
x86_64-linux machine and a very straightforward configuration
(--enable-languages=c++ --disable-multilib) after r191494 I'm seeing the
following libstdc++ regressions.

are all ICEs like the below. Apparently PCHs are required, I can't
reproduce outside the testsuite, without the library PCHs.
Does it make any sense to you? Please let me know if I can somehow help.
Thanks,
Paolo.
