Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|middle-end |c++ Last reconfirmed| |2021-08-25 Status|UNCONFIRMED |NEW Ever confirmed|0 |1 --- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> --- There's nothing the middle end can do to warn because the front end emits code to zero-initialize the struct/class first and only then to use the value of the zero-initialized member to [re]initialize it. The detection needs to happen in the front ends (both C and C++).
