You're mixing up different errors - searching for 'gcc internal error'
isn't particularly helpful.  gcc internal errors happen for lots of
different reasons, not just a single bug.  Random unrepeatable crashes
are almost certainly hardware failure.

The crash on FreeBSD we were talking about earlier is repeatable, and
only happens with GCC 2.95.x.

The crash that happens on your 40 Sparc Ultras is repeatable, right?
It's probably just a compiler bug in the particular version of gcc
you're using.
