<pre>The following code falsely triggers warning for uninitialized object.
#include <cassert>
struct A {
int x;
// A(int a): x(a) {} // If I uncomment this, A is no longer aggregate,
// the warning is gone.
};
struct B:A {
int y;
B(int a, int b): A{a}, y(b) {} // fails to see the aggregate init A{a}
};
int main()
{
B b(1, 3);
assert(b.x == 1);
assert(b.y == 3);
}</pre>
