Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. However, the eager runtime traverses all tensors in the output. Since only one of the tensors is defined, the other one is `nullptr`, hence we are binding a reference to `nullptr`. This is undefined behavior and reported as an error if compiling with `-fsanitize=null`. In this case, this results in a segmentation fault The issue is patched in commit da8558533d925694483d2c136a9220d6d49d843c, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."}, {"lang": "es", "value": "En Tensorflow anteriores a las versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, la operaci\u00f3n \"tf.raw_ops.Switch\" toma como entrada un tensor y un booleano y genera dos tensores. Dependiendo del valor booleano, uno de los tensores es exactamente el tensor de entrada mientras que el otro deber\u00eda ser un tensor vac\u00edo. Sin embargo, el tiempo de ejecuci\u00f3n de eager salta todos los tensores en la salida. Dado que solo se define uno de los tensores, el otro es \"nullptr\", por lo que vinculamos una referencia a \"nullptr\". Este es un comportamiento indefinido y se reporta como un error si se compila con \"-fsanitize=null\". En este caso, esto resulta en un fallo de segmentaci\u00f3n.
