If you try to compile this:
import std.c.stdlib: malloc;
struct Foo {
int x;
int[0] a;
}
void main() {
enum N = 20;
Foo* f = cast(Foo*)malloc(Foo.sizeof + N * typeof(Foo.a[0]).sizeof);
f.a.ptr[10] = 5;
}
You receive:
prog.d(9): Error: null dereference in function _Dmain
As I have said, you have to use operator overloading of the struct and some
near-ugly code that uses the offsetof. I don't like this a lot.
