843366961cf14aad6490fbeb30f7b98f37f8833a may cause segfaults on
Mac OS X. See backtrace below. I only observed the segfault with
-O2 builds.

I have been using git on my OS X box for quite a while, and that  
commit appears to be nearly two months old.  I have yet to see any  
packing errors in any of my repositories.  (This is with -O2,  
which appears to be the default.)

My gcc reports itself as build 5367 instead of 5250.  Perhaps  
there is a compiler error in an older copy of the DevTools?

This seems to be the case. I upgraded the compiler and
tried again. The segfault didn't happen again. Note, this
was not exactly the same situation as before because the
git repository used for testing changed a bit since the
first segfault.

I'll do some more repacking over the day and will report
my observations.

I did a lot more testing and am pretty convinced now that
the problem is not present with the newer compiler. Using
build 5367 of gcc seems to creating a working git executable
while build 5250 creates a broken one.
