Your expectations are wrong. You probably believe that here
-------------
void f3()
{
D d3;
printf("3) getValue() -> %d, ", d3.getValue());
{
D d3 = d3;
printf("getValue() -> %d\n", d3.getValue());
}
}
------------------
the initialization of the inner d3 should happen with the outer d3, but
that isn't so: in the initialization clause, the outer d3 is already no
longer visible. You therefore initialize a variable with itself. This is
a documented way to generate uninitialized variables and at the same time
circumvent the warning that would usually results from this action.
There is a warning -Winit-self in more recent releases that warns about this
specific case. Now, of course the fact that it doesn't trigger on this code
is not very helpful. Have to investigate this...
