Descriptions

When the webdriver for the Browser object downloads data from a HTTP server, the data pointer is set to NULL and is allocated only in curl_write_cb when receiving data. If the server's response is an empty document, then wd->data in the code below will remain NULL and an attempt to read from it will result in a crash.

Cuando el controlador web del objeto Browser descarga datos de un servidor HTTP, el puntero de datos se establece en NULL y se asigna solo en curl_write_cb cuando se reciben datos. Si la respuesta del servidor es un documento vacío, entonces wd->data en el código a continuación permanecerá en NULL y un intento de leerlo provocará un bloqueo.
