Any ideas would be greatly appreciated. I'm assuming this is aarch64 specific?

[lu-zero]

It seems a problem in libgit2, I managed to reproduce it on Gentoo, bumping to cargo 0.50 seem to solve the problem.

I made a new point release, please test it and confirm it works for you as well.

[mdegans]

I can confirm it works, @lu-zero
