Re: git-commit fatal: Out of memory? mmap failed: Bad file descriptor

I got this message from git-commit:

I ran git-bisect and the result is below. Doesn't look like
much help though.

To reiterate, I only have problems with the builtin-commit,
i.e. 1.5.4.*, the 1.5.3.* series works correctly. Of course
if this is a memory corruption issue, then it could just be
that the pattern of memory accesses in 1.5.3 does not tweak
the problem.

The other possibly useful info is that running
'git commit -a -C HEAD --amend' does not cause the error.

    builtin-commit: fix summary output.

    Because print_summary() forgot to call diff_setup_done() after futzing with
    diff output options, it failed to activate recursive diff, which resulted in
    an incorrect summary.

I've spent a number of hours trying to debug this. If there are any other ideas for
debugging, let me know. I'll keep the repo for a while.
