compiler crash building hashed-storage 0.5.3
ghc: panic! (the 'impossible' happened) (GHC version 220.127.116.1100924 for x86_64-unknown-linux): Expected one of wanted constraints (BUG)
This happens with
cabal install hashed-storage-0.5.3, but that's a bit of a pain to reproduce as it depends on dataenc which needs a dependency bump. I cut it down to the attached file which just depends on mtl.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
