    Exception: invalid memory address
    
    I have a customer that receives the above message when displaying the
    mcc_iconic_map from an Ultrix system to a VMS node using DECnet as the 
    transport.
    
    Client:			Server:
    
    DEC5000-260                 4000-VLC
    Ultrix 4.3A                 OpenVMS 6.1
    MCC 1.3.0                   DECnet/OSI
                                Motif 1.1
    
    If the mcc_iconic_map is displayed locally on the Ultrix node ther is
    no problem, however, if the mcc_iconic_map is displayed remotely on any
    one of the VAX systems they see the following.
    
    From DEC5000:
    
    # setenv DISPLAY smog::0.0
    # mcc_iconic_map &
    
    When the map appears they do the following.
    
    1) Open a domain
    2) open an instance of a class they created and added to the class
       hierachy
    3) bring up a toolbox
    4) double click on one of the options to bring up an instance of a 
       subclass
    
    At this point the mcc_iconic_map goes away and they receive the
    following error:
    
    Exception: invalid memory address
    
    IOT Trap     mcc_iconic_map (core dump)
    
    The above scenerio fails remotely to the VAX's but works fine locally
    on the Ultrix node, does anyone have any ideas ???
    
    thanks,

| Hi Dave, I know some problems may occurs with MCC displayed on a server running X11R5 level of protocol and Motif 1.2. As your server is running MOTIF 1.1 this problem is strange. Benoit | |||||

| 6069.3 | What is the x server version | AZUR::DURIF | Tue Nov 22 1994 08:26 | 19 | |
| Hi, I tried to run MCC on an ULTRIX system running ULTRIX 4.3. The display was a VAXstation running VMS 6.1. It runs but may be i did not the same than in .0. The strange thing with .0 is that i thought VMS 6.1 comes with Motif 1.2 not motif 1.1. This is the case for the VMS system i use to display on. .2 The same problem "Exception: invalid memory address" occurs with .2 MCC T1.4 .2 Motif 1.1.3 .2 Ultrix 4.3 May i understand that your X server is also VMS 6.1 Motif 1.1 ?
