Is there any particular reason why you are using 1.5.0? It should be fixed in 1c2ff59df54de0c7ca4abb2e9699159b3b0fae83 which is available in 1.6.0 and 1.6.1.

[tim2CF]

I'm using it just because it was in my version of nixpkgs. I'll try out overlay to 1.6.1, thanks

[tim2CF]

well, it not worked, because of different versions of dependencies, but I think this bug is only test-related and code itself is good? I can just apply dontCheck nix helper to omit tests in 1.5.0

[gromakovsky]

Yes, it's only test-related, I think you are trying to compile tests with hedgehog revision ≥ 1.0.0 and they don't compile due to a change in hedgehog.

[tim2CF]

I'll just use 1.5.0 without tests then, thanks!
