Without pkgs.bitwarden-desktop, it builds without any problem.

Steps to reproduce

When using this flake (https://codeberg.org/karldelandsheere/dotfiles) on a aarch64-darwin host, be sure to add pkgs.bitwarden-desktop to your systemPackages, and darwin-rebuild your system.

Expected behaviour

It should rebuild successfuly.

This is a problem for the maintainers of compiler-rt-libc, not bitwarden-desktop.

@amarshall My bad!

Edit: Fixed in #523142

[karldelandsheere]

@ryand56 Does it mean then that I "just need to wait" for the fix to be merged into unstable?

[ryand56]

Yes, or overriding the package with the changes.

Ok, I need to figure out how to do that haha.
