            Bug ID: 41784
           Summary: volatile copy assignment operator for std::atomic
           Product: libc++
           Version: 8.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: ilya.burylov at intel.com

The code snippet below is compiled.

#include <atomic>

int main()
{
    volatile std::atomic<int> a1;
    std::atomic<int> a2;
    a1 = a2;
}

But shouldn't because copy assignment operator marked as deleted (atomic&
operator=( const atomic& ) volatile = delete) by the C++ standard.
