FIX: The IDispatch::Invoke method in Atlcom.h leaks memory in Windows CE .NET 4.1 (884024)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.1

SYMPTOMS

An application can call Automation methods that are implemented by using Active Template Library (ATL). However, when the application does this, the application increases its total memory usage over time.

CAUSE

The IDispatch::Invoke method implementation in Atlcom.h allocates memory to make function calls. However, the IDispatch::Invoke method does not release memory for some processors.
