 Using ghc 6.10.4, I tried to install the crypto lib (version 4.1.0) via
 "cabal install crypto". However, ghc fails:

 [4 of 4] Compiling Main             ( SHA1Test.hs, dist/build/SHA1Test
 /SHA1Test-tmp/Main.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 6.10.4 for i386-unknown-linux):
         RegAllocLinear.getStackSlotFor: out of stack slots, try -fregs-
