We have this crash triggered fairly often in Mesa lavapipe, by two specific visual tests: https://github.com/ruffle-rs/ruffle/pull/17574#issuecomment-2301759315

It has happened much more frequently with the ubuntu-22.04 GitHub Actions runner, but updating the mesa-vulkan-drivers package from the kisak/mesa PPA on Launchpad has helped a lot then. Now it makes no difference on ubuntu-24.04, and while it's a lot less frequent overall, it's not fixed entirely.

I'm not sure whether this is more of a Mesa or an LLVM bug, but let's start the investigation here.
