          Issue ID: 15266
           Summary: Parameters to methods of final classes become
                    uninitialised in out contracts for DMD only
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: lt.infiltrator gmail.com

--------------------------
final class C {
   void property(uint rate)
   out {
      assert(_rate == rate, "This will fail");
   } body { _rate = rate; }

   this() { }
   uint _rate;
}

void main() {
   auto c = new C;
   c.property = 25;
}
--------------------------

This fails with DMD2.066 and 2.068; but succeeds with GDC2.066.  I haven't
tested with LDC.

Making the class non-final fixes the problem.  As does making property() a UFCS
function taking C as its first parameter.
