FIX: An access violation occurs under low memory conditions in your Visual C++ .NET application

This article has been archived. It is offered "as is" and will no longer be updated.
Under low memory conditions, when you run an application that was created in Microsoft Visual Studio .NET by using Microsoft Visual C++ .NET, the application may experience an access violation and may quit unexpectedly. This problem occurs if the application uses the Microsoft Visual C++ Runtime Library.
This problem occurs because memory allocation failures prevent an internal string buffer from being initialized in the Visual C++ Runtime Library.
