Further simplification:

extern(C) int printf(char*,...);

interface InterfaceB(T) : InterfaceA {}

interface InterfaceA{
  // changing return type to InterfaceA makes it work
  InterfaceB!(Object) func ();
}

class Foo(T) : InterfaceB!(T) {
  InterfaceB!(Object) func() {
    return null;
 }
}

void main() {
  auto foo = new Foo!(Object);

  // without this call, segfault is gone
  foo.func(); 
  printf("foo.func() call passed\n");

  InterfaceA ifA = foo;
  assert(ifA !is null);
  ifA.func(); // segfault
}
