We have uncovered a regression in this commit:

b8a2486f1524947f232f657e9f2ebf44e3e7a243

What version did you test? We used to have problems with multithreaded
index-pack on cywgin because its pread implementation is not
thread-safe, see c0f8654 (index-pack: Disable threading on cygwin -
2012-06-26). Not sure if we fall into the same path on Mac, or this is
something else..

The symptom is that 'git fetch' dies with:

error: index-pack died of signal 10
fatal: index-pack failed

I guess it won't help much, but what if you enable coredump and get a
stack trace from it?

I have only been able to reproduce it on a Mac thus far; will try
ubuntu next.  We can make it go away by running:

git config pack.threads 1
