It appears that TM is not stored on a word boundary. In visual mode, 
disassemble the code and see if the SIGBUS comes on the load instruction.
If it does, do the following on the a.db command line 'tm:a' - that should
print the address of tm. If it is not a word-boundary, and you did not force
it to be there w/ a rep-spec, call your SunAda (Verdix) rep.
