+        The Intel compiler does not support the __has_trivial_constructor type

+        [Qt] Wrong runtime instance objects of wrapped QObjects may be used if
+        the wrapped object died before the gc removed the instance.
+
+        https://bugs.webkit.org/show_bug.cgi?id=31681
+
+        Added a unit-test to verify that wrapping a QObject with the
+        same identity as a previously but now dead object works.
