FIX:Hard-coded breakpoints and RtlGetUserInfoHeap error

ID: Q132492

The information in this article applies to:

The Microsoft Foundation Classes (MFC), included with:
- Microsoft Visual C++, 32-bit Editions, versions 2.1, 2.2

SYMPTOMS

When connecting to a 32-bit SQL Server ODBC data source while running the VC++ debugger under Windows NT 3.51, you may receive messages in the Ouptut window similar to the messages below:


LDR: LdrpMapDll Relocating: Base Name odbccp32.dll
LDR: LdrpMapDll Relocating: Base Name sqlsrv32.dll
LDR: LdrpMapDll Relocating: Base Name MSVCRT10.dll
LDR: LdrpMapDll Relocating: Base Name dbnmpntw.DLL
HEAP: Invalid Address specified to RtlGetUserInfoHeap( 140000, 145aec )

These messages will occur if you are using the SQL Server 4.21 ODBC driver.

Additionally, you may find that the debugger will stop on hard-coded breakpoints (INT 3 assembler instructions).

RESOLUTION

The messages are harmless and can be ignored. After hitting the breakpoints, you can continue by selecting "GO" in the debugger or pressing F5. The Microsoft SQL Server ODBC version 2.50.0121 fixes the problem. You can acquire the latest version of the SQL Server ODBC driver on the SQL Server version 6.0 CD in the \I386\ODBC directory.

STATUS

Microsoft has confirmed this to be a bug in the products mentioned at the beginning of this article. This problem has been fixed in version 2.50.0121 of the SQL Server ODBC driver.
