2914.0. "illegal instruction" by MICROW::LANG () Fri May 01 1992 15:35
I'm working on Ultrix with MCC 1.2 EFT, writing an AM, which
I've been working successfully with for about a month. Today,
I got the following error: This is from running the 2 sessions, one
in debug, although the error occurs without debug.
This occurred after a successful enroll. It is reproducable.

| this smacks of dispatching to a bad address. Make sure
MCC_MMEXE_LOCATION is the same anytime the MM is invoked as it
was when it was enrolled.
Stop at line 467 of routine im__dispatch. Do a machine stepi until
you hit a jalr instruction and then try to step into the routine
and see if it point to a valid instuction.

Thanks, I found out that the dictionary and mar were out of
synch. In the executable (and I assume the mar), the entity name
was 4000, but there was no 4000 in the dictionary.
