hyprcursor_test2 and hyprcursor_test_c tests segfault in Alpine Linux #64

Closed earboxer closed 2 months ago

earboxer commented 2 months ago

Haven't quite figured this out for a while (getting these tests working is my blocking issue for moving Hyprland to community from testing), just thought I'd put this here because someone else might have some input.

(related to free-ing the raw shape data?)
