Las versiones 5.34, 5.36, 5.38 y 5.40 se ven afectadas, incluyendo las versiones de desarrollo de la 5.33.1 a la 5.41.10. Cuando hay bytes no ASCII en el lado izquierdo del operador `tr`, `S_do_trans_invmap` puede desbordar el puntero de destino `d`. $ perl -e '$_ = \"\\x{FF}\" x 1000000; tr/\\xFF/\\x{100}/;' Fallo de segmentaci\u00f3n (volcado de n\u00facleo).
