SYMPTOMS

An access violation may occur when you try to run a Microsoft Visual C++ 2005 application that contains Object Management Group (OMG) Common Object Request Broker Architecture (CORBA) Interface Description Language (IDL) code. Consider the following scenario:
  • You create an application in Microsoft Visual C++ 2005.
  • The application contains OMG CORBA IDL code that is similar to the following:
    abstract interface Drawable {
      long draw();
    };
    valuetype Point supports Drawable{
      public string name;
      public long x;
      public long y;
    };
    
    interface GraphManager {
      Point get_point();
    };
  • You try to run the application.
In this scenario, you may receive the following error message:
The instruction at "0x00401456" referenced memory at "0x00000ede". The memory could not be "read".

CAUSE

This problem occurs when the Visual C++ compiler generates invalid code. The invalid code causes the application to contain a corrupted v-table. Therefore, the application cannot marshal the Point type when the application calls the get_point method. When this problem occurs, the application experiences an access violation.
