dmd git head. I used simpler files:

// a.d
module a;

import c;
import b;

auto foo()
{
     auto c = C!void();
     return c.transmogrify();
}

void main()
{
     assert(.foo() == b.foo());
}

// b.d
module b;

import c;

auto foo()
{
     auto c = C!void();
     return c.transmogrify();
}

// c.d
module c;

struct C(T) {
   int transmogrify() {
     return 42;
   }
}

Then I built the program like this:

$ dmd a.d -c
$ dmd b.d -c
$ dmd c.d -c
$ dmd a.o b.o c.o
