Gnus/5.13 (Gnus v5.13) Emacs/27.0.90 (gnu/linux) |
I updated from master today and now Emacs is crashing when I use Gnus.
The first time it happened I been reading news groups for a while, then
email arrived and when I pulled it into Gnus, Emacs crashed. Then I
restarted Emacs under GDB and now get the crash already on starting Gnus
(with my initializations; it doesn't happen when I start an unconfigured
Gnus in Emacs -Q). I tried to get a full backtrace, but the output of
`bt full' seemed to be in an endless loop; here's the start of the
backtrace:
Thread 1 "emacs" received signal SIGSEGV, Segmentation fault.
