bug#27668: 26.0.50; Crash with display-line-numbers t


From: Robert Pluim
Subject: bug#27668: 26.0.50; Crash with display-line-numbers t
Date: Wed, 12 Jul 2017 15:42:28 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/26.0.50 (gnu/linux)

I've had emacs crash on me twice today with the same backtrace. It
appears to be related to setting display-line-numbers to t, although
I'd been running the scratch/line-numbers branch for a while without
any problems.

It *seems* to happen the second time I do 'C-x C-f' from a buffer that
has display-line-numbers t, although I'm having a hard time coming up
with a reliable reproduction method, nor have a got a recipe from
'emacs -Q' (yet).

I have an example trapped in gdb, let me know if you need more info.
