            Bug ID: 91868
           Summary: wrong location info with -Wshadow on C++ constructors
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bernd.edlinger at hotmail dot de
  Target Milestone: ---

While playing with -Wshadow I saw a wrong location info creating a confusing
warning (but I think other warnings have similar issues):

$ cat test.cc
enum x {a};

struct c
{
  c (x, x);
};

void
foo ()
{
  int xx;
  {
    c xx
    ( a, a);
  }
}
$ $ gcc -Wshadow -c test.cc 
test.cc: In function 'void foo()':
test.cc:14:7: warning: declaration of 'xx' shadows a previous local [-Wshadow]
   14 |     ( a, a);
      |       ^
test.cc:11:7: note: shadowed declaration is here
   11 |   int xx;
      |       ^~
