community/gtk4.0: SIGBUS errors on armv7 and armhf
Programs using GTK4.0 crash at various points with SIGBUS errors on armv7 and armhf.
This can be seen in the pipelines for enabling GTK tests (!31986 (closed)), and I've been able to reproduce it on real hardware - just attempting to run gtk4-demo
results in a crash before the window can even appear.
This could be related to software rendering (llvmpipe) being used in both cases, rather than being purely a gtk4.0 issue, but this might require further debugging. @Newbyte has confirmed this also happens with Lima, see #13604 (comment 224939)
Not entirely sure how to get proper backtraces for this, just trying bt
in gdb
results in "The current thread has terminated."
