            Bug ID: 78956
           Summary: std::thread doesn't fully meet LWG 2097 requirement
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

#include <thread>
static_assert( !std::is_constructible_v<std::thread, const std::thread> );

We also need:

  thread(const thread&&) = delete;=
