          Issue ID: 20781
           Summary: Can call @live function without checking dip1021 rules
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: bugzilla at digitalmars.com

The following should give an error, even when DIP1021 is not set, as calling
@live functions with multiple pointers to the same memory object should not be
allowed.

  void test() {
    int a;
    foo(a, a);
  }

  @live int foo(ref int a, ref int b);
