I have the following code:

[test.d]
import testmod;

void main()
{
	printf("%d ", bar());
	printf("%d ", Tfoo!(int).foo()); // {1}
}

[testmod.d]
module testmod;

template Tfoo(T)
{
	T foo() { return 1; }
}

// C!(int) c_int;                 // {2}
// alias Tfoo!(int) foo_int;      // {3}

int bar() { return Tfoo!(int).foo(); }


When I try to compile this via explicit .obj linking, ie:

dmd -c test.d
dmd -c testmod.d
dmd test.obj testmod.obj

I got error:

testmod.obj(testmod)  Offset 00139H Record Type 00C3
 Error 1: Previous Definition Different : _D7testmod06Tfoo_i3fooFZi

If I comment {1} -  no error, compiling is ok.
If I uncomment {2} or {3} - no error, compiling is ok.

DMD needs template instantiation in module with template declaration?

P.S. When I just execute "dmd test.d testmod.d", I got no errors and all is fine.
