Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All XMS.NET applications using UserId and Password while
    creating a connection and using Unmanaged and Bindings as the
    connection mode
    
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    If UserId and Password were passed while creating a connection
    using XMS.NET, the application ended abruptly because of Heap
    Corrupted Exception.This happened only while using Unmanaged and
    Bindings as the connection mode.
    
    A logic error while handling the UserID and Password structures
    caused a block of memory to be freed twice, resulting in the
    Heap Corrupted Exception.
    

Problem conclusion

  • The XMS.NET classes have been updated to avoid freeing this
    memory twice.
