------- 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():
