A patch to avoid the crash
I'm now porting Firefox to Wayland/Weston on Renesas RZ/G1E.
* Renesas RZ/G1E:

* How to build BSP for it:

* Additional Yocto recipes to build Firefox:

https://github.com/mozilla-japan/meta-gecko-embedded
The version of GTK+ is 3.20.9.
Sometimes tooltip_popup_timeout() in gtk/gtktooltip.c causes crash after
closing a browser window.
Although I'm not sure whether it's Firefox's fault or GTK+'s fault, I think
GTK+ should ensure to avoid the crash. It seems that the code in
gtk/gtktooltip.c doesn't observe destroying GdkWindow after registering a
timeout function, it may be the cause of the bug.
The attached patch seems work fine for me, it can avoid crash on my
environment.
