  again work with PCOMM.
  

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.
