I placed three blocks, redstonetorches and redstone dust like you can see in the screenshot. It was very difficult to mak this screenschot ,because the game crashes instantly after placing the last block.
I expected that it turns into a clock or something like that but not into a crash .
You can make this crash happen again, (I tested this very often) if you build the same construction like shown in the Screenshot, no matter in wich order you place the blocks.

PS: I'm playing on an android Samsung galaxy S4 GT 19515, but it wasn't shown in the list on top of this page.
PPS: I was playing on 0.13.0 Beta Build 2, but it isn't on the list...
