Fixing the crash is easy enough but then this trips over
bug #21388.

Also the test hits the double-prompt issue pointed out in
https://sourceware.org/bugzilla/show_bug.cgi?id=23544#c1

    Fix interpreter-exec crash

    PR mi/10347 points out that using interpreter-exec inside of a
    "define" command will crash gdb.  The bug here is that
    gdb_setup_readline doesn't check for the case where instream==nullptr.

------- Additional Comments From marc dot khouzam at ericsson dot com  2009-07-22 17:06 -------
This crash actually happens when using "interpreter mi" inside a define.
It is not only with hook-stop.  Below is an analysis from Paul P that comes from
  http://sourceware.org/ml/gdb/2009-07/msg00152.html

The problem is that in cli/cli-script.c, execute_user_command(),

instream is set to NULL:



312	  /* Set the instream to 0, indicating execution of a

313	     user-defined function.  */

314	  make_cleanup (do_restore_instream_cleanup, instream);

315	  instream = (FILE *) 0;



and later used for fileno():
