FIX: Cursor Library Memory Leak in Multithreaded Environment

ID: Q171878

The information in this article applies to:

Microsoft Open Database Connectivity, versions 2.5, 3.0

BUG #: 1251/4210 (odbcsdk)

SYMPTOMS

When the cursor library is loaded in a multithreaded application, a memory leak occurs.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Open Database Connectivity versions 2.5 and 3.0. This problem has been corrected in U.S. Service Pack 1 for Microsoft Open Database Connectivity, version 3.0. For more information, contact your primary support provider.

MORE INFORMATION

This problem is created when multiple threads establish connections specifying that the ODBC Cursor Library is to be used. For example, if each thread of a multithread application creates a connection using the SQLSetConnection(hdbc, SQL_ODBC_CURSORS, SQL_CUR_USE_ODBC) statement and subsequently executes it repeatedly, you can use the Process Viewer to observe a memory leak.
