The problem is bigger than it first seemed, and still not fixed.

True, I noticed the problem initially when running a just-built git,
but in fact the distributed /usr/bin/git demonstrates precisely the
same heap corruption as the one I built.  See the further discussion
on http://bugzilla.redhat.com/747377

The underlying bug seems pthread-related.
When I make git grep run without using threads there is no problem.

To demonstrate the problem, run this on a multi-core system, in a
clone of a decent-sized git repository like git's own:

    for i in $(seq 100);do echo $i; timeout 1 ./git grep -q stat;done
