That's an interesting question. The compiler does set void-initialized
member variables to zeros:
struct S { double x = void, y = void; }
void main() {
S s; // x and y are initialized to 0
}
I think this is a bug. Such members should be left uninitialized or
initialized to the default initializer for the type (NaN in this case) or
void initialization should be disallowed for member variables.
