Maybe you applied the patch by hand because the mailer mangled the spaces?
You should have changed this part
hammer_cursor_removed_node(
node, cursor->parent,
cursor->parent_index);
to this
hammer_cursor_removed_node(
node, cursor->node,
cursor->index);
I haven't seen a big problem after applying Matt's patch.
Cheers.
