Nick,
The problem is mach-o specific. The problem persists under mainline
binutils built on OS X. I attached a problematic mach-o which you could try
to disassemble as described previously. The problem is in the function
bfd_mach_o_close_and_cleanup, probably in the only invocation of free in
that function. My guess is that some of the bfd metadata is messed up and
never properly allocated, but I'm not sure. I'll have to do some more
investigation. I'm willing to try to help fix the bug and submit a patch if
I can get some guidance.

Thanks,
Ian
