Subject: bug#5609: 23.1.92; segfault in composition_compute_stop_pos

From: Sven Joachim <[email-masked]>

During the last weeks I experienced several segfaults, mostly in Dired,
but unfortunately I did not run Emacs under GDB.  This time I did.
I visited a file named "Makefile" and started an I-search for
"distcheck" when Emacs segfaulted.  This is not reproducible.
