This is a regression between DMD 2.035 and DMD 2.036. Here is a simplified test
case:

struct Foo {
    Foo bar() { return this; }
}

struct Bar {
    Foo foo;
    Bar opCom() {
        Bar r = { foo.bar() }; // Error caused by this line
        return r;
    }
}

The simple work around is to use D style constructors: Bar r = ( foo.bar() );
or to set the fields manually. However, tracking these down is very difficult
because there is no line number nor easy find/replace.
