I saw Thomas's reply.  Of course, -ffrontend-optimize takes a
different code path through the compiler and rewrites some of
the internal state along the way.  If the source code is fixed,
the ICE goes away.  Why waste time worrying about the cause of
an ICE that clearly should be suppressed in the presences of a
sequence of emitted errors?

I doubt that there are anything side effects.
