[Bug 1527741] Re: oxide-qt 1.11.3-0ubuntu2 FTBFS on armhf due to compiler segfault

[Matthias Klose]

this is not reproducible on the porter boxes.  Please could you point me
to a reproducer on a porter box?

and why do you file a bug report against gcc-5-cross when reporting an
issue with the native compiler?

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

Status in gcc-5 package in Ubuntu:
  Incomplete
Status in oxide-qt package in Ubuntu:
  Incomplete

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.
