OpAssign moves the assigned value onto the heap so this is not the problem.

Also the following code works correctly for me on 2.062.
---
import std.variant, std.stdio;

struct S { int p1, p2, p3, p4, p5, p6; }

void main()
{
    Variant v1 = S(1, 2, 3, 4, 5, 6);
    writeln(v1);
    Variant v2;
    writeln(v2);
    v2 = v1; // assert
    writeln(v2);
}

The bug seems to be in the handler for OpID.copyOut.
