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...
