The following code crashes both DMD 2.048 and 2.049 beta on Windows:

// Module a.d
class Base {
    auto fun() { return 1; }
}

// Module b.d
import a;

class Derived : Base {}

// Command
dmd -c b.d


Any of the following will prevent this bug from being reproduced:

1.  Changing the return type of fun from auto to int.
2.  Passing both modules to DMD at once.
3.  Putting both classes in the same module.
