ghc: panic! (the 'impossible' happened)
  (GHC version 6.12.3 for i386-unknown-linux):
	RegAllocLinear.getStackSlotFor: out of stack slots
   If you are trying to compile SHA1.hs from the crypto library then this
   is a known limitation in the linear allocator.

   Try enabling the graph colouring allocator with -fregs-graph instead.   You can still file a bug report if you like.


Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
