You have hit a nasty Garbage Collector bug in ghc. I (re)discovered it some months
ago too. There is yet some patches to make stuff work on ia64.
I think it will be simpler for you to get gentoo's ia64 binaries (unregisterised)
and bootstrap ghc-HEAD yourself.
We, gentoo, apply patches for ghc-6.12.3 to make magic happen (all gone upstream
In case you will decide to bootstrap stable ghc-6.12.3 the following patches should suffice.
== required patches ==
* GC patch (the critical one, fixes bug you have posted)
* you need to pass -G0 to gcc when you build ghc. Gentoo does
it in a special manner: we add the following to mk/build.mk:
SRC_HC_OPTS += -optc-G0
Your approach might be different. It solves known(?) limitation of small object's
== nice to have patches ==
* remove crufty linker flags in order to able to link ghc on recent binutils
* f.i.w calls on ia64 (fixes terminfo and thus interactive darcs, otherwise it will SIGSEGV)
* If you plan to build haddock using unregistered ghc you'll need one more patch
to export needed API (backported from -HEAD).
