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)?
