something broken just now on git-pull from openbsd to OSX

[Randal L. Schwartz]

I just updated my openbsd's GIT to 1.4.2.g55c3, and now my
git-fetch from there to my OSX fails with a fatal error almost immediately.

What just changed?  What can I check?

git-fetch from other repositories to OSX seems to work fine.

Ahh, it might even be a corrupt repository... here's what
a local git-clone shows:

git-clone ~/Git/stonehenge.git
remote: Generating pack...
remote: Done counting 2610 objects.
remote: Deltifying 2610 objects.
 100% (2610/2610) done
remote: Total 2610, written 2610 (delta 1244), reused 2610 (delta 1244)
error: git-fetch-pack: unable to read from git-index-pack
error: git-index-pack died of signal 11
fetch-pack from '/home/merlyn/Git/stonehenge.git/.git' failed.

What do you want me to try to help diagnose this?

And even more info:

Oops!  That's not good.

Indeed it is not good.

First we would need to see who is dying.

git-repack -a -d -f does:

 - list all the objects that need to be packed by running

	git rev-list --objects --all

 - piping that to pack-objects

 - after that remove old ones (because -d is given)

I am suspecting it is either rev-list or pack-objects, but let's
isolate which first.

	git-rev-list --objects --all >/var/tmp/revlist.out

Does this die?  If not

	git-pack-objects pack </var/tmp/revlist.out

does this die?

Once you isolate which, can you bisect to see where it broke in
recent history (assuming it worked ever on OSX)?
