Forms 3.0 - unaligned access pid= or Memory fault ERRORS

I am trying to create a form to maintain codes. I have successfully created 17 others forms just like this one with the same triggers and procedures...basically the only thing different between the previous forms and this form is the table name and field names. Generating the form always says its fine.

The problem is when running this form, Forms dies and I get either "Unaligned access pid=..." or "Memory fault" as a Unix error. Forms seems to cleanup everything properly.

   Versions:   SQL*Forms           3.0.16.12.8
               PL/SQL (in Forms)   01.00.39.00.01
               RDBMS               7.0.15.4.2
              

Oracle support's answer is to upgrade to version 7.0.16 or 7.1.?. If the other 17 forms would fail I would probably be forced to upgrade, but why do 17 work and the 18th one fail?

I have tried to re-create the form from scratch - still fails. I have tried copying the a good INP file and just changing the table name and field names - still fails. I have created a bare bones forms with no triggers other than a KEY-STARTUP that does "execute_query" - still fails.

Usually I get the error when I press the EXIT key, but it has failed when I was using the DOWN key at different records. I have checked the data and everything seems ok. I tried putting in a KEY-EXIT trigger and turned DEBUG on...it hit the KEY-EXIT trigger and once I press a key - failure!

If anyone can shed some light on this, please do! Thanks in advance.
