            Bug ID: 96997
           Summary: step over in gdb always stops in basic_string(const
                    _CharT* __s, const _Alloc& __a =3D _Alloc())
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: alexis.jeandet at member dot fsf.org
  Target Milestone: ---

Minimum code to reproduce the issue:

#include <iostream>
#include <string>


int main()
{
        std::cout << std::string{"str1"};
        std::cout << std::string{"str2"};
        return 0;
}

Stepping over will stop in basic_string ctor which is unexpected. This is
reproductible with G++ 10.2.1 and 10.2.0 (Fedora 32, 32 and Arch).=20
On the same machine building with clang and debugging with gdb doesn't have
this issue.

g++9 and 8 works as expected.=
