ghc 7.0.1 and 7.1.20101112+ panic building blaze-builder-0.2.0.1
When building blaze-builder-0.2.0.1, ghc 7.0.1 (I've tried ghc 7.1.20101112 and 7.1.20101115 also) spits this:
Building blaze-builder-0.2.0.1...
[1 of 8] Compiling Blaze.ByteString.Builder.Internal ( Blaze\ByteString\Builder\Internal.hs, dist\build\Blaze\ByteString\Builder\Internal.o )
ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.0.1 for i386-unknown-mingw32):
