The ubsan overflow tests seem to have some issues with rounding, which make them a little unpredictable as the compiler changes.  See PR63361 for an example bug report from a different architecture.  It's unlikely that there's anything serious here, at first glance.  If the reason for failure is the same kind of "outside the range of representative values" message having the wrong count, I wouldn't worry about it.  But I can't tell whether that's the case.

Title:
  [Ubuntu 16.04] Enable P9 toolchain

Status in gcc-5 package in Ubuntu:
  Triaged

Bug description:
  This is a feature request to track the inclusion of POWER9 enabled in
  Ubuntu.

  This is required as a building block for POWER9 development in Ubuntu
  16.04. The final goal is to have Ubuntu 17.04 as the primary distro to
  (partially?) support POWER9 machines.

  Mirroring for Canonical awareness. A backport will be required.
