class A()
{
    alias C!() C1;
}
class B
{
    alias A!() A1;
}
class C() : B
{
}

>dmd -c text.d
test.d(9): Error: class test.C!().C has forward references
test.d(7): Error: template instance test.A!() error instantiating

Problem cannot be worked around by rearranging order of declaration. All 6
possible orders exhibit the "has forward references" error.

Might be related to #3834
