           Summary: Template function reference being made without the
                    template body being generated
           Product: D
           Version: 2.031
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: burton-radons shaw.ca


Given these two files (noting that the original file didn't have an error in
it, it just allowed me to cut it down further), a.d:

  struct S (T)
  {
    void m ()
    {
      intentional mistake;
    }
  }

  S! (T) f (T) ()
  {
    return S! (T) ();
  }

b.d:

  import a;

  void main ()
  {
    f! (char) ().m ();
  }

Compile them separately then link them together. The link fails because b.obj
has a reference to _D1a8__T1STaZ1S1mMFZv but doesn't have a COMDAT for it (not
that it could compile it).

It turns out that there actually was a problem with the template; oddly enough
the problem was one that causes the compiler to crash, unlike the banal
semantic error here. So having invalid code appears to be a prerequisite for
this problem to manifest.
