Just received the dump(s) from the customer. They are all basically
the same and occur with the same environmental factors:
- Current process running SYS$SYSTEM:RUNDET.EXE
- Crash occurs because the PC is modified to 00000000.00158304, a
non-existent P0 address.
- Below the crash Interrupt/Exception Frame, there is another
Interrupt/Exception Frame with a saved PC of LIBRTL+73E88
- Crash does NOT occur unless the graphics console is in use
