905.0. "Seg fault with reduced object size debugging" by CXXC::MJHANS (Matthew Hanselman, DEC C/C++) Mon Mar 31 1997 13:59

    This is with C++ V5.6's reduced object size debugging and ladebug 4.0-33:
    
    If you attempt to debug the executable
    
    /usr/users/mjhans/ladebug.905/exxalphaosf/bl36/exe/exx
                     
    and set a breakpoint at "me_stmt.cxx":654, ladebug will seg fault.  
    Rebuilding me_stmt.cxx with "all debug info" cures this.
    
    Note: this is using shared objects.
    
    % ladebug /usr/users/mjhans/ladebug.905/exxalphaosf/bl36/exe/exx

This appears to be fixed in Ladebug 4.0-34.  When you get a new
Ladebug, could you verify this.

Thanks,
