Segfault in the Mesa software rasterizer
Since I have upgraded my virtual machines Fedora 33 and 34 with the latest GTK 3.99.3, most examples of my gtk-fortran project are now crashing with a segmentation fault, generally as soon as they start. Everything was OK with GTK 3.99.2.
In the gtk3 branch of my project, no problem with GTK 3.24.23, on the same machines.
Steps to reproduce
This is not linked to my project, since gtk4-demo is also immediately crashing:
[osboxes@localhost src]$ gtk4-demo Segmentation fault (core dumped)
- GTK 3.99.3-1
- GLib 2.66.2-1
- Fedora 33 and Fedora 34 (Rawhide)
