But the `@sigatom` doesn't fix it, I think :( I'll try minimize the example, because right now, it's a bit too messy to really figure out what's going on! Well,...

Okay I reduced it to: ```julia using Gtk, GLFW using Gtk.GConstants function setup_screen() resolution = (600, 500) name = "GTK + GLVisualize" parent = Gtk.Window(name, resolution..., true, true) Gtk.visible(parent, true)...

Guess it's unsafe indeed :P I was assuming, it's only used just before sending it to write, but it's a bit hard to tell where things go. Maybe it'd be...

Yup, I was thinking to just submit something like #46, but then I got greedy :D

I'd say just merge #46 and leave this unmerged until we find something safer ;)

Thank you :) Yeah I don't see why not ;)

>But EnhancedGJK only works with GeometryTypes!!?! It's usually not too hard to upgrade to GeometryBasics, since most APIs have stayed fairly similar!

Good question... I think those may not be maintained anymore... We can ask, if they want to move the package to JuliaGeometry, so it can be maintained by more people!

>it would be useful to have mutable StructArrays of point Why? Can you give a concrete example?
