I wonder how that patch can cause mismatches. Does it reproduce on one of
compile farm machines (my x86-64 bootstrap works fine so does ia64 on terbium
after fixing the gcc 4.1 issue yeterday).
It would be great to have -fdump-ipa-inline-details dumps of the mismatching
run. Perhaps it will be easy to spot the problem.
