Hi Fengguang,

How new is your GCC? This looks like a bug that was fixed recently (September) in GCC:

  https://github.com/gcc-mirror/gcc/commit/0012c439035bc1d5843e5c8e72c6c5fad357d389

cheers

I'm using Debian's cross gcc 5.2.1:

        gcc-powerpc64le-linux-gnu            5.2.1-14+really5.2.1-13

It may take some time for debian to catchup up with the newer version.

Thanks,
Fengguang

I already opened a Debian bug to track the backport of this fix into
Debian's GCC 5.2.1.
