The problem seems to be here in nodes.cpp. In order to giver better 
error-messages it tries to check the type early, but since the type is 
spoofed it fails. If you compile without debugging it should work ;)

// ECMA 11.2.1a
Reference AccessorNode1::evaluateReference(ExecState *exec) const
{
  Value v1 = expr1->evaluate(exec);
  KJS_CHECKEXCEPTIONREFERENCE
  Value v2 = expr2->evaluate(exec);
  KJS_CHECKEXCEPTIONREFERENCE
#ifndef NDEBUG
  // catch errors before being caught in toObject(). better error message.
  if (v1.isA(UndefinedType) || v1.isA(NullType)) {
    UString s = "Attempted to access property on %s object "
                "(result of expression %s)";
        (void)throwError(exec, TypeError, s.cstring().c_str(), v1, this);
    return Reference::makeValueReference(Undefined());
  }
#endif
