Just to let you know, there are a number of open bug reports for GHC on the x86_64 platform, which seem to indicate some kind of occasional memory/GC problem. I'm probably not going to be able to track this down until after the 6.4 release, but we'll put out a patch as soon as we have one.
Here's an error building ghc-6.4.20050224ghc-6.4.20050224 via Anders' Debian x86-64 ghc, although it doesn't look like a memory/GC problem to my untrained eye:

Can you try building with SplitObjs=NO ?
Wolfgang, Ryan - that looks like a splitter problem, no?
(The splitter is more of a dark art than the evil mangler, I propose we name it the "diabolical splitter" from now on.)

Using SplitObjs=NO gives out many warnings then finally dies with:

Are you building unregisterised? Those messages about global register variables (I think) imply that you are not -- and we haven't yet got x86_64 (terrible name, I much prefer amd64) registerised. Looks like you might even have found the point where registerisation breaks.
Try building unregisterised: GhcUnregisterised=YES
just as the .hc bootstrap compiler was built.
-- Don
Well, I don't know much about how the bootstrap compiler was built (I just downloaded it from http://debian-amd64.alioth.debian.org/pure64/pool/unstable/main/amd64/g/ghc6/), but building with GhcUnregisterised=YES and SplitObjs=NO died with:
