GNU Bison before 3.5.4 allows attackers to cause a denial of service
(application crash). 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.
