Hello.

Spending a few hours on this, this popped up as the bad rev. This
explains why it is OS X only. Unsure what the exact problem is still
but that should be easy from here.

$ git bisect bad
d29658759a1343995f0d8b163d7fe445dd904b81 is the first bad commit

Not easy at all.  I have run with this change since it was made on two separate machines, and I don't see the errors you do.

Does your tree have any local modifications?  Do you see this in the Emacs-24 branch also?
