[Fwd: [Bug optimization/11741] internal compiler error at gcse.c:5318]

[Jens Rehsack]

Maybe at a good time the next snapshot should be imported into
freebsd to get this fix, too :-)
Some ports (eg. mysql40, apache) are switchable to high optimization
where a bug in gcse could cause invalid code which will be removed
with the patch for this bug.
