Package: Emacs

My Gnus session of Emacs on master crashed with the following backtrace:

    Lisp Backtrace:
    "redisplay_internal (C function)" (0x0)
    (gdb) 

I can *currently* reproduce it at will:

    start `emacs -f gnus`, then enter my IMAP password, then press RET
    on the first group (INBOX) and *boom*.

As the backtrace indicates, the crash happens not while running the Gnus
code that enters the group, displaying the summary of all messages, but
in the immediately subsequent redisplay.

If I enter another group, the problem doesn't occur, so I guess it has
to do with the current content of the summary buffer in my INBOX
(i.e. probably due to some unusual email message's title).

The crash happens because of:

      /* We should never cache on backward scans.  */
      if (bidi_it->scan_dir == -1)
        emacs_abort ();

The content of bidi_it is below, in case it helps,


        Stefan
