    ****************************************************************
    FreeTopicString in CSQMOPEN (and CSQMSOPN) tries to free an area
    of storage of address '40404040'x, however this address is
    invalid so CSQSHFMN gets an 0C4. The field containing this
    address is mhnd.pTopicODStr which is a union of another field
    mhnd.csGMOResolvedQName. That field is set to blanks in CSQMOPNI
    if the ObjDesc.ObjectQMgrName is not equal to the local qmgr
    name. The error condition only happens, however, if the
    ObjDesc.ObjectQMgrName is a queue manager alias to the local
    queue manager.
    

Problem conclusion

  • CSQMOPEN and CSQMSOPN will no longer try to free the area
    pointed to be the blanked out pointer pTopicODStr.
