Hi Jonathan,

thank you for reporting the issue!

Are you able to reproduce the issue?

If I understand correctly the backtrace, Vim got SIGHUP and 'vim_handle_signal()' is called as a part of dealing with signals. 'vim_handle_signal()' went well with this signal number as the argument and set 'got_signal' value to '1'.
In the next 'vim_handle_signal()' invocation, when it is called from 'ui_inchar()', it got an segfault on 'kill()'.

I tried to reproduce it with sending SIGHUP via 'kill' to opened 'vim', but without success.

Comment 14 Jonathan Wakely 2020-10-19 10:28:46 UTC
I don't know what caused it, sorry. I don't even remember any vim process crashing or being killed. I just found the report in the abrt client and thought I'd report it.

Feel free to close it if you can't reproduce it.

Comment 15 Zdenek Dohnal 2020-10-19 10:32:46 UTC
Ok, then I'll close it for now. Feel free to reopen if you hit it again.

Comment 16 Jonathan Wakely 2020-10-20 16:41:25 UTC
Ah, I've just realised that this probably happened when I switched network and an ssh connection was closed, sending SIGHUP to the vim process running on the remote host.

I'll reopen if I see it again. Thanks.
