           Summary: dmd SEGV when checking length of Tuple elements when
                    length == 0
           Product: D
           Version: 1.007
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: webmaster villagersonline.com


The following code segfaults dmd 1.007 on Linux:
  template Tuple(Elements...) {
    alias Elements Tuple;
  }
  struct foo {
    Tuple!() elements;
  }
  static assert(foo.elements.length == 0);

Turns out that it SEGVs also when the Tuple is not empty:
  template Tuple(Elements...) {
    alias Elements Tuple;
  }
  struct bar {}
  struct foo {
    Tuple!(bar) elements;
  }
  static assert(foo.elements.length == 1);

The following (nonsense) code also causes a SEGV:
  template Tuple(Elements...) {
    alias Elements Tuple;
  }
  struct foo {
    Tuple!() elements;
  }
  static assert(foo.elements[0]);
