SYMPTOMS

In Microsoft Visual Studio .NET 2003, you create a Microsoft Foundation Classes (MFC) application that uses the CStringArray class and the CStringData class. After the application runs for an extended period, the application may unexpectedly close (crash). When you examine the call stack information, you notice that the application unexpectedly closes when the MFC71u!ATL::CStringData::Release method is executed.

CAUSE

This problem occurs because every time that you call the CStringArray::InsertAt method, the nRefs member is increased by 4. When the value of the nRefs member exceeds 2,147,483,647, the value of the nRefs member becomes negative. A negative value changes the way in which the CStringData class manages shared access.
