Hi Dave;

I have experienced an inconsistent error with all versions of the 8.1
driver up to an including I don't get any error via ODBC but the
Microsoft "Unfortunately Microsoft has encountered an error and must exit
the application..." dialog box.

I have never experienced this problem with the 7.02 branch up to

I installed 7.02.026 on February 22 and did not encounter any problem until
this morning.

I am running PostgreSQL 8.1.0 on i686-pc-mingw32, compiled by GCC gcc.exe
(GCC) 3.4.2 (mingw-special).

I am running a VB.NET 2003 application accessing the database (obviously)
via ODBC.

I cannot find any error notification in mylog or the psqlodbc log. In the
Windows event viewer the error message is:

Event Type: Error
Event Source: COM+
Event Category: Unknown
Event ID: 4786
Date: 28/02/2006
Time: 10:18:37 AM
User: N/A
Computer: DELL4500
The system has called a custom component and that component has failed
and generated an exception. This indicates a problem with the custom
component. Notify the developer of this component that a failure has
occurred and provide them with the information below.
Component Prog ID: 0[ODBC][C:\Program
Method Name: IDispenserDriver::CreateResource
Process Name: FormsTest.exe
Exception: C0000005
Address: 0x036F5AFF
Call Stack:
psqlodbc35w!SQLGetDiagFieldW + 0x2AF

The error is totally inconsistent - I can go for days without experiencing
any problem; at other times it occurs frequently.

Any thoughts?
