Comment 4 Francesco Turco 2016-08-31 22:14:15 UTC 
Patch from comment 3 works for me.
Comment 5 ncahill_alt 2016-09-09 13:57:08 UTC 
I see this has been fixed in wxGTK 3.1.0 with the patch from here: https://github.com/wxphp/appimage/blob/master/wxgtk-gcc6.patch.

I will also mention this in the wxGTK 3.1.0 thread (bug 577030).

Thanks, I'll have a look next week.

This is the correct patch.  If someone wants to apply it go ahead.  I don't have commit access at the moment.
