  89 # To do this, we must shutdown the currently running gdb and restart
  90 # with the -core args.  We can't use gdb_start because it looks for
  91 # the first gdb prompt, and the message we are looking for occurs

  94 # grumbles about (said grumbling currently being ignored in gdb_start).
  95 # **FIXME**

  98 # is apparently a limit on the length of a fully specified path to
  99 # the coremaker executable, at about 80 chars.  For this case, consider
 100 # it a pass, but note that the program name is bad.
