Bug ID: 114675 Summary: warning for "reference to not fully constructed object" Product: gcc Version: 13.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: Simon.Richter at hogyros dot de Target Milestone: --- We have an object that contains several sub-objects that should reference each other through interface pointers. I'd like to make sure that interface pointers given to objects constructed later already point to initialized objects. So, for struct everything { everything() : a(), b(c), c(a) { } A a; B b; C c; }; I'm passing a reference to the not-yet-constructed C object to B's constructor, so this is unsafe despite being legal C++. I wonder if it would be possible to generate a warning here.
