SEGV in Test_syntax_colortest()

[Ernie Rael]

Is this a known issue? Intermittent.

Can you post the output of `:version`?

It's maybe related to a ticket I created a long time
ago: https://github.com/vim/vim/issues/8681
where I sometimes saw a crash and I could see:

Executing Test_syntax_colortest()
Executing Test_windowid_variable()
free(): invalid pointer

Vim: Caught deadly signal ABRT

Vim: Finished.
Aborted (core dumped)

I don't recall a fix for this bug. I just tried the command
that I gave in https://github.com/vim/vim/issues/8681
and sure enough, I still got 1 crash in 100 iterations
(at iteration 80/100). So it's not frequent for me:

$ for i in $(seq 1 100); do echo "=== $i"; make test_gui; done 2>&1 | tee log
...snip...
Executing Test_syntax_colortest()<0d>
Executing Test_windowid_variable()
free(): invalid pointer
Vim: Caught deadly signal ABRT

Vim: Finished.
Aborted (core dumped)

This crash was with vim-8.2.4650 gtk3 GUI on
xubuntu-18.04.6. I'll update the ticket with that
info.

I haven't seen this. How did you build? It may also depend on your
window manager.

Using gcc

The only Makefile change:

-#CFLAGS = -g
+CFLAGS = -g

$ apt-cache policy libgtk-3-0
libgtk-3-0:
  Installed: 3.24.30-1ubuntu1

|$ printf 'Desktop: %s\nSession: %s\n' "$XDG_CURRENT_DESKTOP"
"$GDMSESSION" Desktop: pop:GNOME Session: pop |
