            Bug ID: 99152
           Summary: Wrong type of implicitly captured by-value unevaluated
                    operand
           Product: gcc
           Version: 11.0
               URL: https://godbolt.org/z/sYsTqa
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: oleksandr.koval.dev at gmail dot com
  Target Milestone: ---

This example was taken directly from the
standard(http://eel.is/c++draft/expr.prim.id.unqual#3):

void f() {
  float x, &r = x;
  auto l = [=] () {
    static_assert(std::is_same_v<decltype(x), float>);
    static_assert(std::is_same_v<decltype((x)), const float&>);
    static_assert(std::is_same_v<decltype(r), float&>);

    // fails, decltype((r)) is float&
    static_assert(std::is_same_v<decltype((r)), const float&>);
  };
}
