--- Comment #2 from Franz Sirl <sirl at gcc dot gnu.org> ---
x86_64-linux profiledbootstrap shows a similar symptom (trunk@r14-2929):
during GIMPLE pass: ivcanon
../../gcc/cfgrtl.cc: In function 'bool can_fallthru(basic_block, basic_block)':
../../gcc/cfgrtl.cc:638:1: internal compiler error: in operator>, at
profile-count.h:995

I'll see if I can find time do the requested debugging later.
