Reduced testcase that crashes cc1plus

The minimal testcase attached seems to trigger a stack overflow in cc1plus
(confirmed on both x86_64 and MinGW x86).

This doesn't seem to happen on any gcc 4.7 or 4.4 compilers I've tried, only
the 4.6 series.

Confirmed as working in mainline and 4_7-branch. I'm adding the testcase and
closing the PR.

Done. Note: I have been able to reproduce on 4.6.3 only with -O, thus I'm
adding the testcase to /opt.
