Hi,
When using xboard with gnuchess the gnuchess program seems to consistently
crash after 2 moves using the xboard program.
Tested on -current on amd64.
I asked on #openbsd on IRC and another user could reproduce it on -current too.
Snippet from xboard -debug log output:
[...]

Be6 Qe2

44356 <first : stty: TIOCGETD: Inappropriate ioctl for device
GameEnds(27, Error: first chess program (gnuchess) exited unexpectedly, 2)
Interrupting first
45840 >first : result 0-1 {Error: first chess program (gnuchess) exited
unexpectedly}
45840 >first : force
45840 >first : quit
Reading through this debug log there are lots of messages like "Invalid move:",
"command not supported" and "(NULL)" messages also. My guess is there is maybe
some protocol mismatch or some misconfiguration?
Another issue I noticed is when I copy the example file from
/usr/local/share/examples/xboard/xboard.conf to ~/.xboardrc the xboard program
immediately causes a segmentation fault on startup.
I also noticed gnuchess is out-of-date, the latest version is 6.2.7 (from
2020), while OpenBSD still uses 6.2.5 (from 2017):
http://ftp.gnu.org/gnu/chess/ . But using the latest version didn't help
either.
Below is (not fully-tested) diff to bump gnuchess:
