MPE/ix.  But this is also causing panics on Linux 3.0.1 so
I'm guessing that it is a general problem rather than something
specific to the MPE/ix port.

>How-To-Repeat:
Compile attached program, with or without the commented out
int ii;   Without it compiler generates no errors and does
what an novice C++ programmer would expect it to.  With it
generates a compiler panic.   On Linux 3.0.1 both versions
generate a different compiler panic.
