Parece que se ha lanzado una excepción en algún lugar de mi sistema operativo, supongo que es un seguimiento de pila de algún tipo. El código parece un volcado hexadecimal de algo. ¿Qué es esto exactamente? ¿Hay algo que pueda hacer con esta información para saber exactamente qué salió mal y dónde? ¿Para qué se usa esto?

Entonces hay un vivado allí: es una de las aplicaciones que uso y hay un vbox allí. Estoy ejecutando Debian (y Vivado) en virtualbox.
¿Es esto algo que debería preocuparme? ¿Es esto algo que puedo arreglar?
