Panic when building Crucible
I've encountered a panic, which GHC has asked me to report:
[19 of 21] Compiling Lang.Crucible.LLVM.Translation ( src/Lang/Crucible/LLVM/Translation.hs, dist/build/Lang/Crucible/LLVM/Translation.p_o )
<no location info>: error:
ghc: panic! (the 'impossible' happened)
(GHC version 8.4.3 for x86_64-unknown-linux):
isUnliftedType
r_a4Zsg :: TYPE rep_a4Zsf
Call stack:
CallStack (from HasCallStack):
callStackDoc, called at compiler/utils/Outputable.hs:1150:37 in ghc:Outputable
pprPanic, called at compiler/types/Type.hs:1939:10 in ghc:Type
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
This was when compiling crucible-llvm revision 186mfb7wlz with GHC 8.4.3.
I'm building in Nix with a sandbox, so this should be easily reproducible. The Nix files are available here: https://github.com/siddharthist/galois-haskell-nix/tree/ghc-bug. Just run nix-build -A haskellPackages.crucible-llvm.
