            Bug ID: 96010
           Summary: std::make_tuple called over multiple lines reports
                    lines as "not run"
           Product: gcc
           Version: 10.1.1
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

I hope that the gcov file is self-explanatory:

        -:    0:Source:coverage_test.cpp
        -:    0:Graph:coverage_test.gcno
        -:    0:Data:coverage_test.gcda
        -:    0:Runs:1
        -:    1:#include <tuple>
        -:    2:
        1:    3:auto g(int, int, int)
        -:    4:{
        1:    5:    return 0;
        -:    6:}
        -:    7:
        1:    8:auto f()
        -:    9:{
        1:   10:    return g(1,
        -:   11:            2,
        1:   12:            3);
        -:   13:}
        -:   14:
        1:   15:auto h()
        -:   16:{
    #####:   17:    return std::make_tuple(1,
    #####:   18:            2,
        2:   19:            3);
        -:   20:}
        -:   21:
        1:   22:int main(int argc, char *argv[]) {
        1:   23:    f();
        1:   24:    h();
        1:   25:  return 0;
        -:   26:}

I do not know if this happens for other functions, but with that simple dummy
function the lines were annotated correctly.
