5937.0. "Segmentation Fault in RowColumn.c" by ALFAXP::RETTERER () Thu Mar 06 1997 16:33

    Hello, 
    
    It's me again with yet another customer issue:
    
    This time, I have a customer who has a legacy application (Sybase) that
    ran fine on OSF/1 Unix 3.0 347.  They are migrating their application
    to v3.2-214 and 3.2-41.  They link their application with the following
    libraries:  libX11.a, libXm.a, libXmu.a and libXt.a.
    
    With version 3.2-214 and 3.2-41, their application receives a SIGSEGV
    (segmentation fault) 0x1205e0a5c in ButtonMenuPopDown () at
    RowColumn.c:5037.
    
    Here is the output from a v3.2-214 debug session:
    
    (gdb) break _XmMenuPopDown
    Breakpoint 1 at 0x1205e04c0: file RowColumn.c, line 4900.
    (gdb) commands
    Type commands for when breakpoint 1 is hit, one per line.
    End with a line saying just "end".
    >bt
    >cont
    >end
    (gdb) break ButtonMenuPopDown
    Breakpoint 2 at 0x1205e0930: file RowColumn.c, line 5010.
    (gdb) commands
    Type commands for when breakpoint 2 is hit, one per line.
    End with a line saying just "end".
    >bt
    >cont
    >end
    (gdb) run

    RowColumn.c:5037: No such file or directory.
    (gdb) quit
    
    And here is one from a V3.2-41 debug session:
    
    (gdb) break _XmMenuPopDown
    Breakpoint 1 at 0x1205dd260
    (gdb) commands
    Type commands for when breakpoint 1 is hit, one per line.
    End with a line saying just "end".
    >bt cont
    >end
    (gdb) break ButtonMenuPopDown
    Function "ButtonMenuPopDown" not defined.
    (gdb) run
    Program received signal SIGSEGV, Segmentation fault.
    0x1205dd7fc in _XmMenuPopDown ()
    
    
    We sent him the latest Motif 1.2-3 patches for 3.2 but it has not made
    any difference.  Currently, I am having him try to disable tear_off
    menus in his application to see if this makes any difference.
    
    Any help on this would be greatly appreciated.
