    Priority:  normal    |   Component:  Compiler
     Version:  6.10.1    |    Severity:  normal

-------------------------+--------------------------------------------------
 Attempting to compile SHA1Test.hs in the Crypto-4.1.0 package on Hackage
 generates the following

 ghc: panic! (the 'impossible' happened)
   (GHC version 6.10.1 for i386-apple-darwin):
         RegAllocLinear.getStackSlotFor: out of stack slots, try -fregs-
 graph

 Compiling by hand with
 ghc --make -fglasgow-exts -fregs-graph SHA1Test.hs
 resolves the problem.

 I'm using an Intel MacBook Pro running Leopard (10.5.5).
