--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- For the theory of how I think this should behave, see <https://gcc.gnu.org/ml/gcc-patches/2012-05/msg00419.html> (referring back to <https://gcc.gnu.org/ml/gcc-bugs/2012-04/msg02134.html> and <https://gcc.gnu.org/ml/gcc/2010-01/msg00063.html> for the concept of distance for options overriding each other). That is, -Werror=format-security should act like a -Wformat-security variant, and so all these examples should warn/error. I don't know what the immediate cause of this issue or appropriate fix in the context of the present implementation might be.
