Non deterministic with trellis or subme 6 with crf?

Is this right? It cropped up in another thread and I think I've narrowed the non-deterministic behaviour to using subme 6 or trellis. Only in CRF though, I've tried it in 2-pass and it isn't like this. E6300 B2 and x264 v663 and v667 So is it right or broken? OT, but is it also intended behaviour that using a path that doesn't exist means the encode takes place, but no output is created, rather than just creating the folder?

Also, be sure to run the encode more than twice before calling it a pass. In my experiment (2000 frame clip), I could encode, say, 10 times and get only 4 different files. So there's a chance that 2 will be the same. (Is this what you mean by fail quicker?)

Yeah, by quicker I meant a longer sample had to be taken to make sure it failed, I was using a 1000 frame sample to test the script, but moved to a 3500 to run it. At this length it's consistent across the 3 tests it runs.
