Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Started between 20220508 and 20220515, with file g++.dg/lookup/friend23.C :
$ cat friend23.C
template <class Derived>
struct base {
friend void bar(Derived& d) {
d.bar(); // access in inline friend of friend, ok?
}
};
class derived : base<derived> {
friend class base<derived>;
void bar() {}
};
int main() {
derived d;
bar(d);
}
$ g++-13-20220904 -c friend23.C -mforce-indirect-call -fPIC -fprofile-generate
