--- Comment #12 from Martin Sebor <msebor at gcc dot gnu.org> ---
The documented purpose of -Wformat-overflow=2 is to point out potential
problems, including those where an argument is not known to be sufficiently
constrained.  (Level 1 behaves close to what you expect.)  Level 2 is not
enabled in -Wall or -Wextra and must be explicitly enabled.  Different designe
choices are of course possible but since some projects are using it as is it's
useful as designed.  This is not a bug.
