I found this crash while cross-compiling `ghc` for `armv7l-linux` on an `x86_64-linux` host. The nixpkgs issue is https://github.com/NixOS/nixpkgs/issues/466116.
Reproduction steps:
1. Install Nix
2. Check out [nixpkgs](https://github.com/NixOS/nixpkgs) at latest `master`
3. `nix build .#pkgsCross.armv7l-hf-multiplatform.buildPackages.ghc`
Alternatively, to get a shell in the build environment:
1. Install Nix
2. Check out [nixpkgs](https://github.com/NixOS/nixpkgs) at latest `master`
3. `mkdir build && cd build`
4. `nix develop .#pkgsCross.armv7l-hf-multiplatform.buildPackages.ghc`
5. `genericBuild`
The build will keep going after the failure, so scroll up to find the crash. You can then re-run the failing command with different arguments.
Here is the build log output:
