Manfred -- What was the failure mode? Mis-compiled code, compiler
abort, etc?
The only unrolling bug we've fixed recently was a problem with
find_splittable_givs trying to split givs with a dest_reg that was
created by loop.
(which could cause either a segfault in unroll, or incorrect code).
We fixed this in egcs back in late Nov. I can forward that fix to
gcc2 if the maintainers want to look at it.
