Gnus/5.13 (Gnus v5.13) Emacs/28.0.50 (gnu/linux) |
Re-sent with actual attachment.
I have managed to catch a SEGFAULT in a long-running Emacs in the
debugger. I've been unable to recreate this SEGFAULT on demand, but it
seems to be happening when I am attempting to "reset" gnus after
switching my work VPN on/off. I will keep the gdb session up an running
in case there is some more that can be done with this.
In GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version
