I certainly does change behaviour for me and patchwise this relates to
current CVS+HJ's patch, if I use the sources before this went into CVS, all
is fine with -O2. So, before going on a wild bug hunt in an compiler area
I'm not really familiar with, I would like to know if this is a platform
independent bug. It would be very kind if someone could run the C++
testsuite with -O2 and assure me that everything is OK on x86.
Frankly, I don't understand at all why the C++ testsuite doesn't at least
loop over -O0 and -O2 by default, not to speak of the hiding of ICE's in
XFAIL's...
