For gcc-5.0.0-0.15.fc23.x86_64 the same reproducer hangs due to FD not closed
by the driver but that is a different bug.

Filing as a tracker, I guess it is libcc1 specific so we should fix it.

Interesting that FSF GCC r220934 which should be gcc-5.0.0-0.16.fc23.x86_64
still crashes while that Fedora GCC does not crash.

Fedora gcc is built with --enable-checking=release, so performs less
self-checking than trunk.
