Por lo tanto, al determinar la siguiente posici\u00f3n de geneve_opt, la adici\u00f3n del puntero deber\u00eda realizarse en unidades de char *. Sin embargo, la implementaci\u00f3n actual realiza err\u00f3neamente la conversi\u00f3n de tipos antes de la adici\u00f3n, lo que provoca escrituras fuera de los l\u00edmites en el mont\u00edculo.
