A problem using -O2 with g++4.5.0 and g++4.6.0

Using -O2 option with g++4.5.0 and g++4.6.0, the attached file titi.cc is
crashing.
It seems that the correct behavior is to obtain the following output :
titi : I=

Please find "test.list" attached that summarizes our tests, and also the
assembly code obtained with g++4.5.0 -O2 and g++4.6.0 -O2 :
- titi.g++440-O2.s
- titi.g++450-O2.s
<     movsbl    1(%rsp),%edi
> 	xorl	%edi, %edi

Thanks,
Best regards
