[x265] x265 on Linux , yuv input , "Floating point exception"

[王康]

Hi ,

   I just checkout the latest code version from bitbucket, and compile
yasm-1.2.0, and make. It seems all right so far on both x86 and x64 Debian
Linux.

$ uname -a
Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.35-2 i686 GNU/Linux

$ uname -a
Linux 3.2.0-2-amd64 #1 SMP Mon Jun 11 17:24:18 UTC 2012 x86_64 GNU/Linux

$ gcc -v
gcc version 4.7.2 (Debian 4.7.2-4)

$ yasm --version
yasm 1.2.0
Compiled on Jul 24 2013.

$ x265 -V
x265 [info]: HEVC encoder version 0.3+24-fd4954d7c2ac
x265 [info]: build info [Linux][GCC 4.7.2][32 bit] 8bpp
x265 [info]: detected SIMD architectures SSE2 SSE3 SSSE3

   Then I generate yuv and y4m file using ffmpeg:

 $ ffmpeg -i charlie.mp4 charlie.yuv
 $ ffmpeg -i charlie.mp4 charlie.y4m

   And x265 on yuv file :
 $ x265 charlie.yuv -o charlie.hevc
 Floating point exception

   x265 on y4m file, the size of output file is zero.

$ x265 charlie.y4m -o charlie.hevc
