Probably fixed by patch 6190 (591ca91f0501)?

x265 0.7+216-591ca91f0501 [Windows][GCC 4.8.2][64 bit] 8bpp does not crash  
anymore in all presets, except placebo (crash during the final statistics  
summary).

But quality in default CRF 28 is now a lot worse, files now even about  
half the size as before, in presets {fast..placebo}.

--preset faster: 544.26 kbps, 20.311 dB SSIM
--preset fast: 56.79 kbps, 13.542 dB SSIM
--preset slow: 51.78 kbps, 13.493 db SSIM

(Sintel trailer, 640x272, no additional options except logging)
