x265 HEVC Encoder

Bisection is one of the most common method of finding bugs.
In source file common/x86/asm-primitives.cpp it is function pointers assignment with avx512 code -- from line # 4696 to 5385.
We can turn off (comment) first half of this functions (x265-1.exe) and then second half (x265-2.exe).
You can download avx512-bisect1.7z VS 2015 binaries with diff files -- if x265.exe (from clean sources) hangs, please try x265-1.exe and then x265-2.exe -- it should be that one of them hangs and second not.
Please report back the results (which from the 3 binaries hangs and which not).
