Are you building GHC in a fresh tree now? I'd recommend doing that.

Now I am using a *really* fresh tree. Formerly the compilation of Apply.cmm did not render an instructive error message, just failed for some sort of memory access exception. Now I have:

Uhuh. This means that GHC is attempting to build a registerised version (which is what happens by default). If you don't plan to work on registerised support right now, you could set 'GhcUnregisterised=YES' in mk/build.mk.

Incedentally, registerised support should be quite easy, since I've already done it for x86_64-unknown-linux, where the ABI and toolchain are the same AFAIK, so it might just be a case of enabling x86_64-unknown-freebsd in the right places (ghc-asm.lprl for one, I can't remember if there's anywhere else off hand).
