           Summary: (Another) Error message without a line number
           Product: D
           Version: 2.012
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: diagnostic
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: webmaster at villagersonline.com


The code below actually has two problems with the error messages produced.

This bug is to report the fact that the first error message does not have a
line number or file listed.

dmd 2.012, Linux

BEGIN MODULE "a.d"
  import b;

  import std.stdio;

  template typeof_each(T,TPL...)
  {
    static if(TPL.length == 0)
      alias Tuple!(typeof(T)) typeof_each;
    else
      alias Tuple!(typeof(T), typeof_each!(TPL)) typeof_each;
  }

  template typeid_each(T,TPL...)
  {
    static if(TPL.length == 0)
      alias Tuple!(typeid(T)) typeid_each;
    else
      alias Tuple!(typeid(T), typeid_each!(TPL)) typeid_each;
  }

  void foo(ARGS_TPL...)(ARGS_TPL args)
  {
    writefln("", typeid_each!(typeof_each!(ARGS_TPL)));
  }

  void bar()
  {
    foo(',' , ',');
  }

BEGIN MODULE "b.d"
  template Tuple(TPL...)
  {
    alias TPL Tuple;
  }

END CODE
