struct Foo{
    string field;
}

bool func(string input){
    Foo foo;
    foo.field = input[0..$];
    assert(foo.field == "test");
    foo.field = "test2";//assignment1
    assert(foo.field == "test");//assertion1
    assert(foo.field == "test2");//assertion2
    return true;
}

static assert(func("test"));


This code doesn't work on dmd v2.053.
Somehow assertion1 succeeds and somehow assertion2 fails in CTFE.
This shows that assignment1 has wrong behavior.
