Anyone else use SQLSTRINGCONNECT() to connect to an iSeries using Client Access Drivers?

Starting with update SI53809 to the odbc driver I consistently get C0000005 errors with calls to SQLSTRINGCONNECT...

This from the event log...

Faulting application name: test.exe, version: 0.0.0.0, time stamp: 0x436c0d5a

Thanks for your interest,
