Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |DUPLICATE --- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> --- Overflow in calls to formatted functions with a format string containing directives other than "%s" is not detected at compile time in GCC versions prior to 7. In GCC 7 the overflow is diagnosed even without _FORTIFY_SOURCE or optimization. I don't expect it to be feasible to backport the GCC 7 work to prior versions so I'm going to resolve this request as a duplicate of the already implemented enhancement request pr49905. *** This bug has been marked as a duplicate of bug 49905 ***
