Hi Philip,
Can we please have this particular warning filtered to only our
mailing list? It's another known issue that's emailing unrelated
authors. Sorry, and we'll get it fixed.

sure, and i just checked, it is one code issue at our side, it should
be sent to clang only, but we only judge the error output, and miss
the warning part. I will also fix this in our code.
