Missing categories…

Trying your product, I wanted to test suggestions based on categories, but I miss some categories…
As a matter of fact, the problem comes from extra_func_hierarchical_sort. If I comment the call to this function inside condition_product_category I get all my categories.

I did some debug and all I can end with is that just before the final following:

for($i = $max_depth; $i >= 0; $i--) {
	foreach($terms as $term) {
		if( $term->depth == $i ) {
			if( isset($temp_terms[$term->term_id]) ) {
				$term->child = $temp_terms[$term->term_id];
			}
			if( $i != 0 ) {
				if( ! isset($temp_terms[$term->parent]) ) {
					$temp_terms[$term->parent] = array();
				}
				$temp_terms[$term->parent][$term->term_id] = $term;
			} else {
				$new_terms[$term->term_id] = $term;
			}
		}
	}
}

the $terms array is correct and just after it’s wrong (Before: $terms[14] was parent of $terms[15] to $terms[17] / After: $terms[14] is a copy of $terms[17] -> as a parent is missing, no member of the family gets into $new_terms! Nota: $terms has 17 elements).
I ran some tests, reordering ‘families’ and everytime, the last parent is replaced by the last child… Strange!
Inside this for a ‘child’ key is set for some entries of $terms, so I would bet for a memory problem… A maybe a PHP bug? Very strange as adding a ‘depth’ element earlier in the function did not create any problem.

Or maybe it has something to do with the fact that my last parent slug (and name) starts with a “z”?
