GHC panic when compiling compdata
When testing ghc-7.8.2.20140609 with Stackage, I came across the following ghc panic:
[51 of 62] Compiling Data.Comp.Ordering ( src/Data/Comp/Ordering.hs, dist/build/Data/Comp/Ordering.o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.8.2.20140609 for x86_64-unknown-linux):
Loading temp shared object failed: /tmp/ghc4836_0/ghc4836_257.so: undefined symbol: compdatazm0zi8zi1zi0_DataziCompziDeriveziUtils_zdwabstractConType_info
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
