6069.0. "Exception: invalid memory address" by CSC32::D_MAHDER () Thu Aug 04 1994 15:14

    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,
    dave mahder

6069.1	problem may be related with motif version	AZUR::DURIF		`Fri Aug 05 1994 04:04`	8
	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
6069.2	mcc T1.4 too!	BACHUS::DEWILDE	Patrick	`Mon Nov 21 1994 10:59`	11
	Hi, The same problem "Exception: invalid memory address" occures with MCC T1.4 Motif 1.1.3 Ultrix 4.3 any hint? thanks, Patrick
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 ?
