FIX: Execution of sp_OACreate on COM Object Without Type Information Causes Server Shut Down (282279)

The information in this article applies to:

Microsoft SQL Server 2000 (all editions)

This article was previously published under Q282279

BUG #: 351375 (SHILOH_bugs)

SYMPTOMS

SQL Server contains a set of system procedures "sp_OA..." to allow interaction with COM objects.

If the COM object does not support type information, SQL Server logs an access violation exception reading address 0x00000000 and then shuts down the computer. The top of the stack trace fill contains the following:

Module(odsole70+00003A2B) (CCachedTypeInfo::~CCachedTypeInfo(void))
Module(odsole70+000038FF) (CCachedTypeInfo::`scalar deleting destructor')
Module(odsole70+000029DE) (CODSOLEThreadInfo::UnlinkCTypeInfo())
Module(odsole70+000027DD) (CODSOLEThreadInfo::~CODSOLEThreadInfo())
Module(odsole70+000049EB) (OAUninitialize())
Module(sqlservr+0046A624) (PSS::ResetFromBatch())

CAUSE

When the COM object does not support type information, the sp_OA stored procedures attempt to free a NULL pointer, causing the exception to occur.
