           Summary: 64-bit libmudflap.c++/pass55-frag.cxx FAILs at -O

It seems that there's only one libmudflap test failing on most targets:

FAIL: libmudflap.c++/pass55-frag.cxx ( -O) execution test

It only fails for 64-bit multilibs and only at -O, -O[023] does work.

I wonder what to do about that. I do have a patch to XFAIL the test, but
strangely it turns the FAIL into a PASS, not XFAIL.
