Problem conclusion
When PCSWLIB.DLL allocates memory it calls MapViewofFileEx on a block of virtual addresses. This entire block is supposed to be free at the point of allocation. The existing code had no check to verify the availability of this memory block. The code changes introduces this check by asserting ownership on the block about to be allocated. Fixed in Manufacturing Refresh PCOM 5.9.6.0
