Qbits

I am trying to understand why the LabVIEW compiler (when creating intermediate files) is having problems when shifting the data back around in a loop. If I don't use a shift register it compiles fine. My thought is that this has something to do with dynamic dispatching, but since the data type isn't changing between iterations (when using the shift register) it should be fine. Attached is the code (LabVIEW 2012). Does anyone have any insight why I'm having a problem? Thanks. Test FPGA.zip
