Subject: bug#39207: 28.0.50; crash when sending gnus message

From: [email-masked] (Gĳs Hillenius)
Date: Tue, 21 Jan 2020 10:43:29 +0100

I started afresh, repeated the gnus mail bug I described in the previous
message, got emacs-snapshot to hang, stopped it with kill -SIGUSR2
emacs-snapshot,

and then ran 'bt' as requested.

Hope this helps.
