+++ This issue was initially created as a clone of Issue #8016 +++

Testcase:

m1.d
---
module m1;

import m2;

private void t(alias Code)()
{
    return Code();
}

void f()
{
    t!( () { } )();
}

// The forceSemanti() and static assert is only needed to reproduce it in D2
bool forceSemantic()
{
    f();
    return true;
}

static assert(forceSemantic());

void main()
{
}
---

m2.d
---
module m2;
import m1;
---

dmd -c m1.d
dmd -c m2.d
dmd -ofm m1.o m2.o
m2.o: In function `_D2m11fFZv':
m2.d:(.text._D2m11fFZv+0x0): multiple definition of `_D2m11fFZv'
m1.o:m1.d:(.text._D2m11fFZv+0x0): first defined here
collect2: ld returned 1 exit status
--- errorlevel 1

nm m1.o | grep ' T'
0000000000000000 T _D2m113forceSemanticFZb
0000000000000000 T _D2m115__unittest_failFiZv
0000000000000000 T _D2m11fFZv
0000000000000000 T _D2m11fFZv9__lambda1FNaNbNfZv
0000000000000000 T _D2m17__arrayZ
0000000000000000 T _D2m18__assertFiZv
0000000000000000 T _Dmain

nm m2.o | grep ' T'
0000000000000000 T _D2m11fFZv
0000000000000000 T _D2m11fFZv9__lambda3FNaNbNfZv

I think neither D2m11fFZv or _D2m11fFZv9__lambda3FNaNbNfZv should be defined in
m2.

Confirmed to be D2-only.
