Compiling the Haskell bindings for ROSE causes a ghc panic

I tried to build the ROSE compiler infrastructure project (rosecompiler.org) on my Debian box. I managed to coerce everything else into at least appearing to work, but when GHC was compiling the Haskell bindings module, it crashed and asked me to report the crash as a bug, so I am doing so. I should note that the configure script supplied with ROSE refused to configure in the absence of GHC 6.10 until I edited it, so perhaps this issue is known, at least to the ROSE team (or maybe they had something else in mind). Anyway, I am reporting the bug like I was told.

I'm running Debian Squeeze on x86_64, GHC version 6.12.1. Here is the relevant portion of the output from make:

ghc: panic! (the 'impossible' happened)
  (GHC version 6.12.1 for x86_64-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
Debian-specific note: please remove old .hi files and try again.
For details, see /usr/share/doc/ghc6/README.Debian

I also enclose the offending source file as an attachment, in case that will help.

Thank you,

Source file that caused the reported ghc panic

Carrying out the suggestion of compiling with -fregs-graph (by the mechanism of adding {-# OPTIONS_GHC -fregs-graph #-} to the offending source file) produces this:

Thanks for the report. However, this looks like a duplicate of #1993 (closed), and should work in more recent versions of GHC thanks to #2790 (closed).

If you still have problems with GHC >= 7.4.1, please reopen.
