I'm facing the same random crashes than you on Fedora 36 and the crash dump has the same backtrace.

Good catch, I didn't notice that. I'll keep firefox running for a while, maybe this happens on my machine too.

Also, could someone please compile this app manually, try to wait for another crash, and post the dump here? The binaries built from the AUR have stripped all their debug information, so the crash dumps lack some important information.

I have the same issue but I dont use Firefox, Arch Garuda

I don't have crashes with compiled jamesdsp from git.
