It looks like the recent differential builds are all failing like this:
compiler/main/DynamicLoading.hs:79:19: warning: [-Wunused-matches]
Defined but not used: ‘hsc_env’
79 | initializePlugins hsc_env df
ghc: panic! (the 'impossible' happened)
(GHC version 8.2.1 for x86_64-unknown-linux):
typePrimRep (r_apc3 :: TYPE rep_apc2)
CallStack (from HasCallStack):
prettyCurrentCallStack, called at compiler/utils/Outputable.hs:1133:58 in ghc:Outputable
callStackDoc, called at compiler/utils/Outputable.hs:1137:37 in ghc:Outputable
pprPanic, called at compiler/simplStg/RepType.hs:360:5 in ghc:RepType
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug make: *** [compiler/stage1/build/PrelRules.o] Error 1
make: *** Waiting for unfinished jobs....
make: *** [all] Error 2
Oddly, I don't see a commit to master failing like this. What's going on?
