Emacs dumps core in Gnus with gnus-uu-mark-thread

Emacs dumps core in Gnus with gnus-uu-mark-thread

[Julien Cubizolles]

In recent versions, Emacs is crashing whenever I run gnus-uu-mark-thread in a
*Summary* buffer, and even when accessing some groups from the *Group*
buffer. Also the *Summary* modeline gets funky when ticking a message,
marking it unread...

I've never seen anything like it.

The relevant version numbers are:

GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.12,
cairo version 1.16.0) of 2020-01-22

Gnus v5.13

I don't have this problem rolling back to:
GNU Emacs 26.3 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.11) of
2019-09-23, modified by Debian

Julien.

Can you run emacs under gdb and get a backtrace? Also, do you have any
settings for gnus-read-mark and similar using unicode emoji?

Yes good catch ! I had all of my gnus-whatever-marks, and
gnus-sum-thread-tree-whatever set to unicode characters. Without it, the
problem disappears. Is there a bug report about it ?

Yes, Bug#39207. I just posted a suggestion there that helps for me with
the gnus-whatever-marks, but Iʼll need to check if something similar
is needed for gnus-sum-thread-tree-*

No idea if it's the same problem, but my bug#33345 has to do with
a crash in Gnus linked to Unicode chars (no gnus-uu-mark-thread, tho).

A proper fix has since been checked into emacs-master:

    Author: Paul Eggert <eggert@cs.ucla.edu>
    Date:   Wed Jan 22 23:43:29 2020 -0800

        Fix crash when sending Gnus message (Bug#39207)

I'm using it at the moment, it's working fine, thanks.
