--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
r244326 adds LTO to -Walloca-larger-than, -Wformat-length, and
-Wformat-truncation, making the -Walloca-larger-than warning work with LTO. 
Even though the gimple-ssa-sprintf pass seems to run with -flto the other two
warnings still don't work for some reason.  I've raised bug 79062 to track
that.
