RenderToTexture with RectangleTexture causes Runtime Error and presents black screen

Question

Problem Description:
Please see RTTtest.as first(https://bugbase.adobe.com/index.cfm?event=bug&id=3776210), run time error occurs on iOS devices ( I have test two devices: iPad2 and iPhone 5 )
Error: Error #3604: Sampler 0 binds a texture that is also bound for render to texture.
at flash.display3D::Context3D/drawTriangles()
at RTTtest/RenderTT()[C:\RTTtest\src\RTTtest.as:274]
at RTTtest/_OnEnterFrame()[C:\RTTtest\src\RTTtest.as:243]
Lines between 159~189 present some of my testing results, some are correct and the others are incorrect.
In addition, I also have test "On AIR Simulator" and nexus 7 2013, the error does not produces.
Steps to Reproduce:
1. directly executes the RTTtest.as on iPhone 5.
will see the error ( on debug mode )
2. Commenting line:169-170, and un-comment line:172-178 does not produce error.
Actual Result:
if ignoring the error, the render texture presents black, therefore the screen presents black.
Expected Result:
The testing program draws two triangles, the one is blue, and the other is red.

If you have updated to win 8.1 and you get the error message "the system cannot find the file specified" it is a known problem.  The work around is
