Fedora & Alpine build segfaults due to vapoursynth (master)

[voidastro4]

I build av1an master on Fedora 40 successfully.

When running the result: Segmentation fault (core dumped)

valgrind -v av1an suggests the culprit may be vapoursynth:

vapoursynth provided by Fedora repos.

Building vapoursynth from git master and using LD_PRELOAD to force av1an to use it did not help.

I tried the same thing with Alpine Linux.
Alpine Linux doesn't even have libvapoursynth so I built it from master.
Compiled fine.
Same error.

Seems like av1an is extremely brittle and only Arch is supported?

Av1an Release source from 2 weeks ago same result

[lutoma]

I'm running into the same error on Fedora 41. Both when using cargo install av1an and when doing a cargo build --release in the repo
