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.

Ugh, we need that base class to make assignment operators work correctly.

I suppose making it public won't hurt.

libstdc++: Add testcase for std::pair as a structural type [PR 97930]
This PR was fixed by r12-221-ge1543e694dadf1ea70eb72325219bc0cdc914a35
(for compilers that support C++20 Concepts) so this adds the testcase.

Fixed on trunk by using concepts for std::pair in C++20 mode.
For GCC 11 (and maybe 10) just changing the base to public is probably OK.
