    Richard,
    
      By its nature, cr_restart has to do some pretty "unconventional" 
    stuff.  However, I am suprised that it is crashing.  The program 
    cr_restart is really only a requester for the restart, so I am not sure 
    how valuable it is to run gdb against cr_restart.  What you really 
    probably want it a way to attach the debugger to the restarted process.
      We don't have any currelty known issues or work-arounds related to 
    debugger use.  I encourage you to enter into bugzilla a detailed 
    description of your problem and we'll see if it is something we can address.
    
    -Paul
