I think this should be fixed in gcc - see:
https://bugzilla.redhat.com/show_bug.cgi?id=531385
Long story short - this is the result of gcc's "-combine" being
fragile. It's possible to avoid by compiling seabios with "make
COMPSTRAT=1". We may need to change the default.
Ughh - did FC12 go out without this fix?
