I've been able to get mwm (the one in /usr/athena in 6.3B) to core
dump on the VAX (anubis, specifically), by causing multiple windows to
go away in a short period of time... like clicking away a bunch of
zephyrgrams quickly.
Core dump is in /afs/athena/mit/wesommer/core.mwm; a traceback in adb
seems to show a partially trashed stack (the last four stack frames
repeat ad nauseum); the cause of death is a segmentation violation, as
it tried to dereference a bogus pointer.

I can reproduce this at will.
