 Summary of the bug:

 Using a variety of ffmpeg builds I have recently run into a scenario on a
 new server my client is using where executing any encode using libx264
 like the following line I get an Assertion Failed error which appears to
 look like the look up for SSE3 instruction set is failing even though it
 is clearly available.

 ffmpeg.exe -i file.mp4 -vcodec libx264 -y -f mp4 file.f4v

 Yields:

 Assertion failed!

 Program: D:\Applications\Virtuosotv\Recordings\ffmpeg.exe
 File: /home/kyle/software/ffmpeg/pkgs/x264/source/x264-git/common/cpu.c,
 Line 248

 Expression: !(cpu&(X264_CPU_SSSE3|X264_CPU_SSE4))

 How to reproduce:
 {{{

 Can only reproduce on a very specific new server, works everywhere else I
 have it. I could start a remote session with an engineer if necessary.

 }}}
