--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
This looks like a near dupe of bug 72783 (or vice versa), though not exactly
the same. That one asks for hardening which will be harder. Warning should be
a lot easier. The file where -Wformat-overflow is implemented for sprintf et
al. is gimple-ssa-sprintf.c. -Wformat alone is handled in c-family/c-format.c
but that's not a good place to do buffer overflow checking (it runs too early
to have knowledge of object sizes in all but the most trivial cases).
