SYMPTOMS
If you run the PowerSoft PowerBuilder Watcom database engine DB32W.EXE in a separate VDM, a General Protection Fault (GPF) occurs when another application tries to access the database through DB32W.EXE. In tests with Microsoft Query, the GPF occurred in <unknown> at 00C7:B40A.
CAUSE
When another application sets up ODBC, PowerBuilder's DB32W.EXE passes it a 16:16 pointer what is valid only in the VDM where DB32W.EXE is running.
RESOLUTION
DB32W.EXE will run in a separate VDM if you check the Run In Separate Memory Space box in the Program Item Properties dialog box in Program Manager. It will also run in a separate VDM if you launch it with the START command. Run the querying application and DB32W.EXE in the same VDM.
STATUS
This behavior is by design.
