La matriz se inicializa con cuatro elementos, que corresponden a las cuatro llamadas a stream_enc_regs() en el inicializador de la matriz. Esto significa que los índices válidos para esta matriz son 0, 1, 2 y 3. El mensaje de error 'stream_enc_regs' 4 &lt;= 5 a continuación indica que hay un intento de acceder a esta matriz con un índice de 5, que está fuera de los límites. Esto podría provocar un comportamiento indefinido Aquí, eng_id se utiliza como índice para acceder a la matriz stream_enc_regs. Si eng_id es 5, esto daría como resultado un acceso fuera de los límites en la matriz stream_enc_regs. De esta forma se soluciona el error de desbordamiento de búfer en dcn401_stream_encoder_create.
