Signal 11 when compiling at -O2

The attached code results in a Signal 11 when compiled at -O2,
it passes at -O1.
It faults in verify_dominator() in loop.c at line 2559 because
JUMP_LABEL returns 0.
Could somebody please verify that this isn't just my egcs version
failing ?
This is the CVS version from 3rd April, compiled with
-O2 --mcpu=k6 --march=k6 -fschedule-insns2
here's the output from --verbose:
