A bug report upstream might be nice here too, or if not I might get to it someday :)

@rdp As of ba57a46 BtbN/FFmpeg-Builds started using x265 version 3.6, and it did not cause any problems in their build script, I wonder maybe if this problem is related to this build script, or somewhere around the compilers that this build script uses.

is that older so still working?

@rdp No, they are using the new one, the one that uses if(X86MATCH GREATER "-1") in the CMakeLists.txt, and their x265 build script is working properly with ASM.
