Hello,
I hoped this issue was solved by recent modification to fstat/stat,
but sadly it doesn't seem so. To fix this driver bug (and it is a
driver bug only AFAIK), use for building gcc, g++, gfortan, etc for
CFLAGS=-O0
This solves this issue. The question here is what produces the issue
here. Maybe you could add to gcc's build the option
-Wstrict-aliasing=2 option, too (for -O2 build) and check if there are
any new strict aliasing failures are shown.
Best regards
Kai
