NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison."

NOTA: hay un riesgo s\u00f3lo si Bison se usa con una entrada no confiable, y un error observado resulta causar un comportamiento inseguro con un compilador/arquitectura espec\u00edfico. Los informes de errores estaban destinados a mostrar que un choque puede ocurrir en el propio Bison, no que un choque puede ocurrir en el c\u00f3digo que es generado por Bison"
