To elaborate on that: Starting in 2.7 parts of the submodule stuff
has been rewritten in C, in 2.8 even more and there is more in flight for

However your bug is also to be found in 2.6, which doesn't contain any recent rewrites, so it is a rather long standing bug, I would presume.

As a workaround for now:

    echo "gitdir: ../gitdir/.git" > .git

instead of the symbolic link in your example (works in 2.6 and also in 2.8.0-rc0)
