This string comes from column-number-mode.  But if I invoke
column-number-mode, I still cannot reproduce the problem, so there's
something else at work here.  Can you describe what you do to
reproduce the crash?

Also, please show what the following commands produce:

 (gdb) frame 3
 (gdb) p bidi_it->charpos
 (gdb) p bidi_it->next_for_neutral
 (gdb) p bidi_it->prev_for_neutral
 (gdb) p bidi_it->bracket_pairing_pos
 (gdb) p bidi_it->bracket_enclosed_type
 (gdb) p bidi_cache_idx
 (gdb) p bidi_cache_start

Thanks.
