The following reduced code example fails to link. It seems to be due to DMD
checkin 12bb9afb753ad2f2aef65550b960357c63854cbc -- fix Issue 10441 - Static
libraries too big. Compiles fine if I try with one version before that.

On my Linux x64 box I get:

$ rdmd test.d
/tmp/.rdmd-1000/rdmd-test.d-C130B18713BE4647AF6BF8F764A06FDD/objs/test.o: In

undefined reference to
`_D3std5array25__T5emptyTS4test3Bar3FooZ5emptyFNaNbNdNfxAS4test3Bar3FooZb'


// test.d Reduced code example:

class Bar {
  import std.container: BinaryHeap;
  BinaryHeap!(Foo[]) Heap;
  struct Foo {
    int opCmp(Foo ) {
      return 1;
    }
  }
}

void main() {}

Kenji, it's not a full solution. 
I've make test case from my project.
It's too strange test case, but as it is.

A.d:
import C;
import D;

void foo() {
    Vector2 rsm;
    readWriteVariable(rsm);
}

void main() {
}

B.d:
import D;

import std.algorithm;


void bar() {
    Vector2[] tc;
    sort(tc);
}

C.d:
import std.traits;

void readWriteVariable(T)(ref T data) {

    foreach(it; __traits(allMembers, T))
            enum vValid = mixin(`is(FunctionTypeOf!(T.` ~ it ~ `) ==
function)`);

}

D.d:
struct Matrix(T, uint _M) {
    int opCmp()(auto ref in Matrix b) const {
        return 0;
    }

    pure auto opDispatch(string s)() {
        enum L = s.length;
        Matrix!(T, L) ret;
        return ret;
    }

    pure Matrix normalized() {
        return Matrix();
    }
}

alias Matrix!(float, 2) Vector2;


Problem exists only if files compiled into single objs and then linked
together.

If something is removed from test case, then linking is ok.

OK, I confirmed the issue. And updated the PR to fix it.
