Se conoce la ubicaci\u00f3n, lo que hace que el seguimiento de la pila sea in\u00fatil. 3. Se produce un bloqueo si se configura p\u00e1nico_on_warn. Tambi\u00e9n es digno de menci\u00f3n que el uso de WARN no est\u00e1 documentado y debe evitarse a menos que exista una justificaci\u00f3n cuidadosamente considerada para su uso.
