[Bug debug/37726] New: [4.4 Regression] Even at -O0 -g debuginfo for vars mentioned in nested fns is not emitted

[jakub at gcc dot gnu dot org]

int foo (int parm)
{
  int var = 0;
  int bar (void)
  {
    return parm + var;
  }
  parm++;
  var++;
  return bar ();
}

int
main (void)
{
  return foo (4) - 6;
}

at -O0 -g this was perfectly debuggable in 4.3, but doesn't know anything about
parm or var, neither in the outer nor inner function.

This test does not work for darwin for some reason, I have not looked why
though, I bet it is due to the way dwarf2 is outputted there.
