When building the latest `opencv-extra` library on OS X I'm getting a GHC panic. To reproduce git clone https://github.com/LumiGuide/haskell- opencv, make sure Nix is installed and execute:
{{{
nix-build -A haskellPackages.opencv-extra ... [11 of 11] Compiling OpenCV.Extra ( src/OpenCV/Extra.hs, dist/build/OpenCV/Extra.p_o ) ghc: panic! (the 'impossible' happened) (GHC version 8.6.3 for x86_64-apple-darwin): Data.Binary.Get.runGet at position 8: Invalid magic number "INPUT(-l" CallStack (from HasCallStack): error, called at libraries/binary/src/Data/Binary/Get.hs:351:5 in binary-0.8.6.0:Data.Binary.Get }}}
The library builds successfully on Linux.
