          Issue ID: 13053
           Summary: Wrong warning on implicitly generated __xtoHash
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: diagnostic
          Severity: regression
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: k.hara.pg gmail.com

Test case:

 system:
struct S
{
    int[] a;
}

Output:
Warning: toHash() must be declared as extern (D) size_t toHash() const nothrow
 safe, not nothrow  system uint(ref const(S) p)

The error message is pointless and has no line number.
