Hm, I would think that the segfault is due to something else than a 
missing instruction.
CVAX has all usual instructions (no need to emulate anything).

The rmpage panic is more likely to be the root cause; it's a fail in the 
page removing routine.
It may be because of something in the real CVAX do not behave as simh, 
especially in the
cache or TLB.  It's a request for removal of a mapping where the mapping 
itself cannot be found.
