Other examples don't crash. Though unless you run task_issue.jl like this: julia -L task_issue.jl, it closes immediately.

Also, when doing compile_incremental with PackageCompiler, it segfaults as well, though I tried it with the drawing.jl GtkReactive example (that example works ok, apart from also needing to be run with julia -L).

Edit: trying compile_incremental on the 2048.jl example from Gtk.jl segfaults as well.

I was experiencing segfaults with GLFW.jl also, so I opened an issue there as well. It already has some insight into the problem, and it's probably the same one. A straightforward fix is not apparent yet though. JuliaGL/GLFW.jl#183

This has turned into a sort of double-post, sorry about that.

Solved here.
