[x265] Segfault when trying to encode yuv444p raw input file

[Manjunath Sripadarao]

Hello,
 I was trying to encode a file in the yuv444p format. x265 crashes when I
give this file as input, it works correctly if I convert the raw file to
yuv420p format through ffmpeg.

This is the command-line I am using

./x265 piece.y4m -o piece.h265

I am using the head of the hg trunk.

This is backtrace I was able to collect.

I tried a raw yuv file too and get the same error

Is there a fix for this bug ?

Thanks,
