  2. A memory leak occurs in an MFC application that is developed by using Visual Studio 2008 SP1 when the CPngImage::LoadFromBuffer method is used

A memory leak occurs in an MFC application that is developed by using Visual Studio 2008 SP1 when the CPngImage::LoadFromBuffer method is used

Symptoms

Consider the following scenario:
  • You run a Microsoft Foundation Class (MFC) application that is developed by using Visual Studio 2008 Service Pack 1 (SP1).
  • The MFC application calls a CMFCRibbonBar class to implement ribbon bars.
  • The ribbon bars contain categories and buttons that use Portable Network Graphics (.png) images as resources.
  • You repeatedly open and close a document that has customized ribbon bars.

In this scenario, a memory leak occurs in the MFC application. Therefore, the memory usage of the application increases.

Cause

This problem occurs because memory that is allocated by the CreateStreamOnHGlobal function in the CPngImage::LoadFromBuffer method is not freed. The expected behavior is that the memory is freed after a stream that is created by the CreateStreamOnHGlobal function is released.
