tcIfaceGlobal panic building HEAD with 6.12.2
This is bad, because we can't build HEAD with the newly released 6.12.2. It was reported a few days ago by Matthias Kilian on cvs-ghc, but at the time we didn't realise it was a regression in 6.12.2.
ghc: panic! (the 'impossible' happened)
(GHC version 6.12.2 for x86_64-unknown-linux):
tcIfaceGlobal (local): not found:
