My recurse_tree function is creating "phantom nodes" (i.e. Tree:Nary nodes with an empty {data} field ) both when I take in the subtree node by reference, and when I take it in by value, i.e.:

# By reference
my $root_address = shift;
my $root = $$root_address;

[download]

AND
# By value
my $root = shift;

[download]

both lead to creating of phantom nodes in my N-ary tree. These tend to be close to the top of the tree, but print-traversal of my Tree::Nary tree shows they are not the immediate children of my Tree's root. Also debug statements that use the Tree::Nary->n_nodes function show these phantom nodes are being made in my recurse_tree() function and nowhere else. Neither recurse_tree nor its helper, find_subtree(), use the Tree::Nary append or prepend functions.

I am on vacation but as soon as I can I will post a copy of my recurse_tree() function here.

Thank You,
