Looks like a bug to me - please file one in bugzilla.
Nope. It's not a bug. S contains a pointer, namely the context pointer
for main.
https://dlang.org/spec/struct.html#nested
Which does not explain why my code compiles if I remove the destructor.
If the struct is POD, there is no need to include the context pointer.
void main()
{
struct POD { int x; }
pragma(msg, POD.sizeof); // 4
struct Nested { int x; void someMember() {} }
pragma(msg, Nested.sizeof); // 16
}
