Bug ID: 106756
Summary: Overbroad friendship for nested classes
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: herring at lanl dot gov
Target Milestone: ---
Sometime since 12.2, GCC has started accepting
struct A {
struct B {
friend int f(B*) {return i;}
};
private:
static int i;
};
despite the express limitation in [class.nest]/4 (/3 in the latest draft).
(Current Clang also accepts it, but ICC and MSVC do not.)
