Your application may quit if the following conditions are true:
- You load an XML document repeatedly.
- You release the IXMLDOMDocument interface pointer.
- The application is multithreaded and uses MSXML2.FreeThreadedDOMDomcument30 or MSXML2.FreeThreadedDOMDomcument40.
- The application forces memory allocation in the high memory range (between 2 GB and 3 GB).
If your application quits, you may receive an access violation with one of the following error messages:
The instruction at 0x77f05130 referenced memory at 0x00000004. The memory could not be "read".
-or-
The instruction at 0x77f05148 referenced memory at 0x96ac3ce4. The memory could not be written.
NOTE: You must compile an application that is written in Microsoft Visual C++ with the
/LARGEADDRESSAWARE switch if the application must use a memory address space that is larger than 2 GB.
The MSXML parser uses the pointer cache to manage objects for garbage collection. The pointer cache does not account for values greater than 2 GB.
