Comment(by gwright):

 I have ghci from HEAD working, built 64 bit on OS X 10.6.  At least it
 works well enough to define `fact` and `fib` at the prompt and get the
 right answers.  (Certainly an improvement over a segfault or abort trap!)

 I'll resync with HEAD and apply my patches, then run the testsuite.  There
 may still be some other problems with the linker lurking, since there have
 clearly been paths through the code that were never exercised in the 64
 bit Mach-O case.

 The final change to fix the crash wasn't much; better to be lucky than
 smart.
