Git rebase hits "Out of memory, malloc failed" error

When I tried to rebase a repo:

git rebase XXX YYY

I get an "Out of memory, malloc failed" error:

First, rewinding head to replay your work on top of it...
fatal: Out of memory, malloc failed (tried to allocate 34537367 bytes)

git encountered an error while preparing the patches to replay
these revisions:

    3d5a7259c57b6b8a86fd6f7c44e6efa25a0e9db4..450ac9a6cf85475ab1a38b763f2f9a836a
4ba6a0

As a result, git cannot rebase them.

If I use cherry-pick it works without an error:

git checkout XXX
git cherry-pick YYY

I was using Git on Windows version 1.9.4-preview20140815. The machine has 8GB RAM, there is no file larger than 100MB in the repo, and the following are settings related with packing:

[core]
    packedGitWindowSize = 256m
    packedGitLimit = 256m

[pack]
    packSizeLimit = 2g
    threads = 2
    deltaCacheSize = 256m
    windowMemory = 256m

First, 1.9.4-preview20140815 is not the latest git version any more. You can download the latest version here.

Also, if you believe Git is using more than 4GB of ram wihin Cygwin 32bits, you can switch to Cygwin 64bits
