On linux, the current compile reports 8 / 16 / 16. As far as I understand this,
this is correct. Did not test windows though.

In DMD 2.066.1, I get:


import std.variant: Algebraic;
static assert(double.alignof == 8); //  Error here, this should be 4.

struct Foo { double x; }
alias Algebraic!(Foo) AFoo1;
static assert(AFoo1.sizeof == 12);
struct AFoo2 {
bool b;
double x;
}
static assert(AFoo2.sizeof == 16);  // Error here, it should be 12.
void main() {}

I'm not sure what that means though.

That's the problem. I think AFoo1.sizeof has to be 16 byte, to respect the
algnment of doubles that is 8.
