I don't think it is useless. In the OP example, while(0) is uncovered because
there is never a "fallthrough exit" of that scope. Consider something like this
where coverage of while(0) is useful.
int fun(int x)
{
do
{
if (x != 0)
break;
if (x != 1)
break;
if (x != -1)
break;
mightThrow(x);
}
while (0);
return x * x * x;
}
