Patch candidate

For reduced test-case:

$ cat test.cc
struct A { static int foo () { return 1; }; static int bar () {
  int x;
  return 2; } };

int main()
{
  return A::foo () + A::bar ();
}

I now have:

$ cat test.cc.gcov
        -:    0:Source:test.cc
        -:    0:Graph:test.gcno
        -:    0:Data:test.gcda
        -:    0:Runs:1
        -:    0:Programs:1
        2:    1:struct A { static int foo () { return 1; }; static int bar () {
        -:    2:  int x;
        1:    3:  return 2; } };
------------------
_ZN1A3fooEv:
        1:    1:struct A { static int foo () { return 1; }; static int bar () {
------------------
_ZN1A3barEv:
        1:    1:struct A { static int foo () { return 1; }; static int bar () {
        -:    2:  int x;
        1:    3:  return 2; } };
------------------
        -:    4:
        1:    5:int main()
        -:    6:{
        1:    7:  return A::foo () + A::bar ();
        -:    8:}

Which is correct in my opinion. Can you please Dmitry test the patch?
