Bug ID: 114078 Summary: operator new and operator delete are incorrectly acceptable as explicit object member functions Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: accepts-invalid Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: de34 at live dot cn Target Milestone: --- GCC currently accepts this wrong program while it shouldn't (https://godbolt.org/z/7jGnGqYPM), because member operator new/operator delete are always static member functions. #include <cstddef> #include <new> struct S { void* operator new(this std::size_t); void operator delete(this S*, std::destroying_delete_t); operator S*() const; operator std::size_t() const; }; int main() { S{}.operator new(); S{}.operator delete(std::destroying_delete); } Similar to https://github.com/llvm/llvm-project/issues/82249 which is fixed recently.
