To reproduce: use M1 and julia 1.7, add Gtk, run tests.

Please don't open issues about missing libraries on M1, there is JuliaPackaging/Yggdrasil#2763 collecting all of them

[bhalonen]

Thanks, I just was trying to figure out where this needed to go when I poked at it a little.

Last week I saw there is a new version of GTK3. I was planning to build it for M1 as JuliaCon project, but for the record that means GTK3_jll will be julia v1.6+ only.

[bhalonen]

I'm using 1.6 for all of my development right now, so for me that is no big deal. Appreciate the infrastructure work.

And here is ImageView.jl running on an M1, powered by Gtk.jl:

very cool. My macbook is 7 years old and needs an upgrade....

Do you remember when it was 15 seconds (#466)? 😄

However it isn't all good, there are some occasional random crashes that proved to be hard to track: JuliaLang/julia#41440

If one needs something more reproducible, check out the history of CI on GtkObservables. That should have plenty of segfaults to examine :-). Unfortunately I haven't yet succeeded in capturing them on my own laptop.
