SYMPTOMS
You try to bind too many parameters to an Open Database Connectivity (ODBC) statement handle. Later, when you clean up the statement handle, you may receive an access violation in your application.



CAUSE
The access violation condition occurs when the SQL_DESC_COUNT header field is set to a value that is larger than 64 KB.

Note This hotfix introduces a new behavior where the value of the SQL_DESC_COUNT header field is examined for a valid value.
