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?
