+// <rdar://problem/7283567> False leak associated with call to
+// CVPixelBufferCreateWithBytes ()
+//
+// According to the Core Video Reference (ADC), CVPixelBufferCreateWithBytes and
+// CVPixelBufferCreateWithPlanarBytes can release (via a callback) the
+// pixel buffer object. These test cases show how the analyzer stops tracking
+// the reference count for the objects passed for this argument. This
+// could be made smarter.
