I cannot guess at the rest of the trouble, but this one is usually
caused by trapping a routine after a `return' instruction but before
the return has completed.  In particular, clobbering the stack will
have this effect.  Since the local variables are below the current
stack pointer, dbx thinks they are no longer available.  If you
use adb you can still find them, though this is hardly convenient.
