If so, > please let me know. Hello Karel! 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. http://code.haskell.org/~slyfox/ghc-ia64/ghc-bin-6.12.3-ia64-haddock.tbz2 http://mirrors.kernel.org/gentoo/distfiles/ghc-bin-6.12.3-ia64-haddock.tbz2 We, gentoo, apply patches for ghc-6.12.3 to make magic happen (all gone upstream and ghc-7.0/ghc-7.0.1) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ 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) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-storage-manager-fix.patch?revision=1.1&view=markup * 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 section size. == nice to have patches == * remove crufty linker flags in order to able to link ghc on recent binutils http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-fixed-relax.patch?revision=1.1&view=markup * f.i.w calls on ia64 (fixes terminfo and thus interactive darcs, otherwise it will SIGSEGV) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-use-libffi-for-foreign-import-wrapper.patch?view=markup * If you plan to build haddock using unregistered ghc you'll need one more patch to export needed API (backported from -HEAD). http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ghciless-haddock-3558.patch?revision=1.1&view=markup Good luck! -- Sergei
