Title:
  oxide-qt 1.11.3-0ubuntu2 FTBFS on armhf due to compiler segfault

Status in gcc-5 package in Ubuntu:
  Fix Released
Status in oxide-qt package in Ubuntu:
  New

Bug description:
  We tried doing a no-change rebuild of oxide-qt 1.11.3-0ubuntu1
  (versioned as 1.11.3-0ubuntu2) and the build failed on armhf only. The
  reason is a compiler segfault:

  In file included from ../../../../third_party/chromium/src/third_party/webrtc/common_audio/signal_processing/downsample_fast_neon.c:13:0:
  /usr/lib/gcc/arm-linux-gnueabihf/5/include/arm_neon.h: In function 'WebRtcSpl_DownsampleFastNeon':
  /usr/lib/gcc/arm-linux-gnueabihf/5/include/arm_neon.h:6831:10: internal compiler error: Segmentation fault
  (...)

  Full log and build link here: https://launchpad.net/ubuntu/+source
  /oxide-qt/1.11.3-0ubuntu2/+build/8458995

  Looks like the previous oxide-qt successfully built version was built
  against gcc 5.2.1 while this time gcc 5.3.1 is used.

  This is critical for us to fix as multiple Ubuntu Touch landings are
  now blocked due to LP: #1527544 - and the no-change rebuild is
  required to fix the broken situation.
