GP Fault or Access Violation When Buffer Too Small

• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

You may receive a general protection fault (GP fault) or access violation (AV) in an application when arranging arrays of interface pointers. The engine puts the array itself in the buffer twice.

CAUSE

The first time random values are used, meaning the array is skipped, and then the next time actual pointer values are used. This causes the engine to GP fault because the buffer is not big enough when all the pointers are NULL.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:
