A memory leak may be generated when you pass a SafeArray as a parameter in Windows 2000 Server

This article has been archived. It is offered "as is" and will no longer be updated.
When you pass a SafeArray as a parameter to a function call that requires data to be marshaled on a Microsoft Windows 2000 Server-based computer, a memory leak may be generated.
This issue occurs if an exception is generated when the Oleaut32.dll file unmarshals the contents of the SafeArray. Exceptions are not handled correctly when a remote procedure call (RPC) calls the Oleaut32.dll file to unmarshal the contents of the SafeArray. Any data that was successfully unmarshaled before the exception occurs is not freed. Therefore, a memory leak occurs.
