mold 2.39 segfault on darwin #407674
Description
Nixpkgs version
- Unstable (25.05)
Steps to reproduce
Mold on darwin builds, but is not able to link linux objects. Mold is not supported for linking darwin objects, but it used to work fine for linking linux objects (when cross-compiling).
Previously discussed in:
Seems to be unique to nixpkgs as it reportedly works fine on homebrew.
