--- Comment #1 from Martin Nowak <c...@dawg.eu> ---
Turns out this is actually a regression introduced by
https://github.com/dlang/dmd/pull/5292.

Also here is the test case with an assertion instead of writeln.

cat > bug.d << CODE
struct Vector
{
    this(ubyte a)
    {
        buf[] = a;
    }

    ubyte[] opSlice()
    {
        return buf[];
    }

    ~this()
    {
        buf[] = 0;
    }

    ubyte[4] buf;
}

void bar(ubyte[] v)
{
    assert(v[0] == 1);
}

void main()
{
    bar(Vector(1)[]);
}
