The tree's not being updated because 64-bit on freebsd doesn't work yet,
as you found. I believe a fix for the mmap() problem has been committed
for the upcoming 6.10.2.
Yes.

The patches haven't been merged into stable yet, but you can grab a HEAD
snapshot and try that instead - we'd appreciate the testing.
I checked out and translated the head version of ghc today from darcs.
It compiled fine. When I now try to start the ghci I get the following:
---- snip ----
GHCi, version 6.11.20081126: http://www.haskell.org/ghc/ :? for help
ghc: internal error: loadObj: failed to mmap() memory below 2Gb; asked for 626688
bytes at 0x40000000, got 0x801635000. Try specifying an address with +RTS
-xm<addr> -RTS
(GHC version 6.11.20081126 for x86_64_unknown_freebsd)
Please report this as a GHC bug:

Abort (core dumped)

If it helps somehow, you can find the core dump here:
http://www.alios.org/~alios/ghc.core.bz2
That's odd, because 6.8.3 is using 0x40000000 on FreeBSD and is working
fine (or is it?).
Ideally I need to find out what the memory map is for GHCi. I posted some
instructions for doing this on Linux/Xen, maybe you can adapt these to work
on FreeBSD:
http://www.haskell.org/pipermail/glasgow-haskell-users/2008-November/016091.html
The bit that needs to change is 'cat /proc/<pid>/maps' - does FreeBSD have
something similar?
Also you could try doing as the error message suggests, and specify a
different address. e.g.
ghci +RTS -xm30000000
ghci +RTS -xm50000000
for 0.75 and 1.25GB respectively.
Cheers,
Simon
