GHC: 8.4.2
free: 5.0.2
LLVM: 5.0.2
Target: aarch64-apple-ios

I'm going to put this log here. I'm not sure if "free" is actually at fault or maybe GHC or even LLVM but something wrong is going on. This only happens on iOS currently & may be due to a misconfigured compiler.

builder for '/nix/store/5r9syyf6grd89mhvlxh0309dsc8hqg39-free-5.0.2-aarch64-apple-ios.drv' failed with exit code 1

Looking through the last source (https://github.com/ekmett/free/blob/master/src/Control/Comonad/Trans/Coiter.hs) & nothing weird seems to be going on.
