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

  94 # if it is empty, this confuses gdb with an empty argument that it
  95 # grumbles about (said grumbling currently being ignored in gdb_start).
  96 # **FIXME**

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