@fbarchard -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

A tsan race for cpu_id.cc was fixed, which would affect this function.  Is there an ongoing issue?

Its not clear what the issue could be in libyuv?
The change referred to changed from hard coded constants to a constant matrix passed by pointer.  I should have declared it as const * so i could try that.

ran tsan on libyuv_unittest and no errors were encountered.
gn gen out/Release "--args=is_debug=false is_tsan=true"
ninja -v -C out/Release
