Preemptive EOF when pushing (using Msys git and PuTTY)

[Gustaf Hendeby <hendeby@isy.liu.se>]

Hello everyone, and thanks for all your dedicated work with git.

I have used git for quite some time now, mainly on different Linux
platforms, without any problems.  Recently we convert the office's pet
project from svn to git.  Many people at the office use Windows (Msys
git 1.6.2 and plink), and I have stared to see (only from Windows
people) problems when pushing similar to the following:

Counting objects: 422, done.
Compressing objects: 422, done.
Writing objects: 100% (379/379), 77.77 KiB, done.
Total 379 (delta 310), reused 371 (delta 303)
fatal: early EOF
error: unpack failed: index-pack abnormal exit
To jkoehler@serv-4100:/git/argos.git
 ![remote rejected] jk/ellipseFit -> jk/ellipseFit (n/a (unpacker error))
error: failed to push some refs to
'jkoehler@serv-4100:/git/argos.git'

There seems to be no problem with the repo, neither local nor remote,
but for a specific setup the problem is reproducible on several Windows
machines, but if I move the whole local repo to a Linux machine instead
the problem is gone.

I suspect the problem is that a ^Z EOF gets embedded in the pack to be
transported, and that somehow interacts poorly with PuTTY, but that is
just my guessing.  And if so I don't know how to handle it.

Has anyone experienced anything similar?  If so, is there any simple fix
to the problem?  How would I go about to try to debug this?
Unfortunately, this seems to happen on a regular basis and affects the
git experience in a negative way, so I would be really happy to be able
to resolve the problem.

I'm thankful for any help that I can get.
