When compiling the latest version of Emacs, I encountered a warning
about my GTK+ version during the configuration phase:
> configure: WARNING: Your version of Gtk+ will have problems with
> closing open displays. This is no problem if you just use
> one display, but if you use more than one and close one of them
> Emacs may crash.
This seemed curious to me, so I dug in a little deeper and noticed that
this part of the configure script was written in 2008 and was supposed
to warn users of GTK+ 2.8 and earlier, released in 2005. I'm using GTK+
3.14.
I wrote a tiny patch to fix the check.
(Maybe the whole warning should be removed? Is there someone still using
GTK+ 2.8 or older?)

IIUC This Gtk+ bug is still open. Or am I confusing this with another issue?

The bug is still open. It looked like it was fixed for 2.10 (it did not crash), but that might have been a fluke.
Its easy to crash Gtk+ with multiple displays. They just don’t care about the issue.

It sounds like Emacs's configure.ac is still wrong.
It's warning for gtk2 < 2.10, or any gtk3.
That seems like a nonsensical combination.
Cf emacs.c's 'due to a long standing Gtk bug...' warning,
which it seems to issue whenever USE_GTK is defined, regardless of
version.

Oh. I haven’t encountered this bug and assumed that it was fixed in 2.10.
Is there an open bug filed in GTK+ bugzilla for this? \x10I tried to search for something that matches the description but I came up empty.

If this affects everyone, maybe this warning should be replaced with an entry to etc/PROBLEMS?
