Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed| |2021-10-13 Ever confirmed|0 |1 Status|UNCONFIRMED |NEW CC| |msebor at gcc dot gnu.org, | |siddhesh at redhat dot com --- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> --- I'm not sure how feasible it is to change __builtin_object_size or to add an option to control this behavior but I agree that treating all trailing arrays as flexible array members is overly permissive and unhelpful (GCC warnings like -Warray-bounds are stricter and treat only zero and one-element arrays that way). Let me confirm this request and CC Siddhesh who just submitted a patch for __builtin_dynamic_object_size. Maybe that's a way toward something stricter.
