A work around is disable the warning, or disable jpeg.

set GYP_DEFINES=buildtype=Official target_arch=x64 libyuv_enable_svn=1 
libyuv_disable_jpeg=1
call python gyp_libyuv -fninja -Gconfig=Release_x64 -Gmsvs_version=2015 
libyuv_test.gyp
ninja -C out\Release_x64

Wrong bug number for the blocking chromium issue. It should be 440500.

I'm unable to repro?
The source code in jpeg casts a pointer to an int and then checks if its a 
multiple of 16.  Its safe enough and used to cause a warning, and now doesnt.
Closing as invalid.
