           Summary: explicit class cast breakage in 1.007
           Product: D
           Version: 1.007
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: default_357-line at yahoo.de


Consider the following code:
import std.stdio;

class A { }
class B : A { }

void main() {
  A test=new B;
  writefln("Test is ", test.toString);
  A test_2=cast(A)(new B);
  writefln("Test 2 is ", test_2.toString);
}

What we would expect to see is "test7.B" twice.
However, what we see is "test7.B" and "test7.A", which of course completely
breaks polymorphism.

The error doesn't appear on 1.005, so it was introduced either in '006 or '007.
