This code breaks on dmd git HEAD:

import std.typecons;

struct B(T)
{
    T a;
    @disable this(this);
    mixin std.typecons.Proxy!a;
}
struct S
{
    B!int a;
}
void main()
{
    B!S b;
}

-------
This code is compilable on dmd 2.062.

That is introduced this commit:
https://github.com/D-Programming-Language/dmd/commit/391addfda30738089ca220f0d9f025e3842deb1f

Simplified test case:

struct B(T)
{
    T val;
    @disable this(this);

    bool opEquals(this X, B)(auto ref B b)
    {
        pragma(msg, "+", X, ", B = ", B, ", ref = ", __traits(isRef, b));
        return this.val == b.val;
        pragma(msg, "-", X, ", B = ", B, ", ref = ", __traits(isRef, b));
    }
}
struct S
{
    B!int num;
}
void main()
{
    B!S b;
}
