--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. The default constructor appears to be used in the definition of
fibonacci_heap::replace_key_data (fibonacci_node<K,V> *node, K key, V *data):
...
/* If we wanted to, we do a real increase by redeleting and
inserting. */
if (node->compare_data (key) > 0)
{
delete_node (node, false);
node = new (node) fibonacci_node_t ();
insert (node, key, data);
return odata;
Having a test case showing what breaks because of it would provide motivation
to fix it.
