Hybrid 2018.05.22.1 - constant crashes using x265

[Selur]

Looking into it, seems like something is wrong with x265, since '--max-ausize-factor' but it should be:
https://x265.readthedocs.io/en/latest/cl...ize-factor

The x265 version which comes with Hybrid has these options:

                                    - 2 : Functionality of (1) + irrespective of size evaluate all angular modes when the save encode decides the best mode as angular.

....

But the version you used, doesn't.
The current version with Hyrid should be '2.8+1-478bfe2b7673', but the version you used is '2.6+22-ff02513b92c0'.
-> Did you replace the x265 version that came with Hybrid with an older one?
