From 79d3f17b07884cc9486f5e6fb21beea97c153a55 Mon Sep 17 00:00:00 2001 From: Damien Lebrun-Grandie Date: Wed, 22 May 2024 17:43:45 -0400 Subject: [PATCH] libstdc++: the specialization atomic_ref should use the primary template Per [atomics.ref.int] `bool` is excluded from the list of integral types for which there is a specialization of the `atomic_ref` class template and [Note 1] clearly states that `atomic_ref` "uses the primary template" instead. libstdc++-v3/ChangeLog: * include/bits/atomic_base.h (__atomic_ref): Do not use integral specialization for bool.
