APAR status

• Closed as program error.

Error description

• Product : Rhapsody 8.1.5
  OS : Windows 8.1
  Visual Studio : 2010
  Library Type : LIB
  
  Customer made a program that designed in Rhapsody 8.1.5 into a
  Library and link it to a Visual Studio MFC project.
  According to memory leaks detection functionality in Visual
  Studio, memory leak detected in the using just following code.
  
  OXF::initialize();
  OXF::cleanup();
  
  If create a library in Rhapsody, it does not matter if they make
  it generic. However, if create an Animation version of the
  library to see what is being animated, and then call it from MFC
  program and exit, a memory leak appears.

  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The leak occured because "_omCloseHandle" string was not     *
  * free. It is saved as a part of AOMThread instance, connected *
  * to OMHandleCloser thread.                                    *

Problem conclusion

• Explicit destruction of animation proxy AOMThread  instance
  added to OXF::cleanup function for OMHandleCloser singleton
  object.
