Yesterday I updated my sources to the current darcs version. Now the build works
again, but there still seems to exist a problem with memory allocation:

--- snip ---
 $ ghci
 GHCi, version 6.11.20090105: http://www.haskell.org/ghc/  :? for help
 ghc: mmap 28672 bytes at 0x40099000: Invalid argument
 ghc: Try specifying an address with +RTS -xm<addr> -RTS
--- snip ---

The ghci does not coredump anymore like it did in my first posting.
I also tried specifing different addresses with the -xm switch without success.

Here is the memory map just after start:
