Bug ID: 97930
Summary: pair is not a structural type
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: stinkingmadgod at gmail dot com
Target Milestone: ---
template<std::pair<int, int>>
struct S;
This is valid in C++20, but fails due to libstdc++ using a private base
__pair_base, rendering pair non-structural.
[pairs.pairs]
pair<T, U> is a structural type if T and U are both structural types.
