I don't have one; I can try reducing the original app's code but that may take a while, the kernel is big.

I tried reproducing the pattern I thought was relevant using some functions from mfma_loop but I can't get it to create that two copy pattern. I will try digging a bit more, but is a end-to-end test necessary here?
