git fsck failure on OS X with files >= 4 GiB

I first noticed this with "2.4.9 (Apple Git-60)", but it reproduces with git built from 37023ba381b6d251d7140a997b39b566dbc63c42.

Create two files with just 0s:

-rw-r--r-- 1 espindola staff 4294967296 28 Oct 11:09 exactly-4gib -rw-r--r-- 1 espindola staff 4294967295 28 Oct 11:09 one-less-than-4gib

and run

git init git add one-less-than-4gib git commit -m bar git fsck git add exactly-4gib git commit -m bar git fsck

The first fsck will run with no problems, but the second one fails:

error: packed cfdaf54c9ccfd8f5e4cee562f7d5f92df13d3106 from .git/objects/pack/pack-ff08480fd7f767b6bd0aeb559f0f5dea2245b0b3.pack is corrupt

Using the very same revision on freebsd doesn't cause any errors.
