SYMPTOMS
You may receive an access violation under rare conditions when the following are true:
 * Your program calls the UpdateBatch method of an ActiveX Data Objects (ADO) Recordset object.
 * The connection that the Recordset object uses is made by using the Microsoft OLE DB Provider for ODBC drivers in Microsoft Data Access Components (MDAC).

You may see a call stack that is similar to the following if you capture the access violation exception with a debugger or in a dump file:

msdasql!CUpdateQueryBased::ClusterRows+0x142

msdasql!CUpdateQueryBased::Update+0x181

msdasql!CImpIRowsetUpdate::Update+0x44c

msadrh15!CRowsetHelper::Update+0x5d

msado15!CRecordset::_UpdateBatch+0x21b

msado15!CRecordset::UpdateBatch+0x8e



This problem does not occur in other OLE DB providers.
