Re: [PATCH/WIP 3/7] fast-import: fix a data corruption in parse_ls

True.

But if it's run for a intermediate
node in parse_ls, node's parent versions[0] can become invalid as it
references it's children versions[0].

A puzzle: when would parse_ls() call store_tree() on a subdirectory?
The store_tree() call is preceded by

	tree_content_get(root, p, &leaf);

which makes a deep copy of "root" in leaf (which seems to be leaked

--- oops).
