Does not require -unittest

struct Foo {
    int a;
    float b;

    Foo func()() const { return this; }
}

auto f1()(Foo a) { return a; }

void main() {
    auto a = Foo(0, 1);

    cast(void)(f1(a.func!()()) == a);
}

Produces this ast for main:

Foo a = Foo(0, 1.00000F);
cast(void)((Foo __inlineretval2 = Foo a = Foo __inlineretval1 = ref Foo this =
a
;
 , (assert(&this, "null this") , this);
 , __inlineretval1;
 , a;
 , __inlineretval2).a == a.a && (Foo __inlineretval3 = Foo a = Foo
__inlineretva
l1 = ref Foo this = a;
 , (assert(&this, "null this") , this);
 , __inlineretval1;
 , a;
 , __inlineretval3).b == a.b);
return 0;

The most suspect thing is that __inlineretval1 is declared twice - the crash in
symbol.c happens on this symbol with assert(s->Ssymnum == -1); - ie the symbol
is already numbered.
