Title:
  link failure when package is built with -O3 (14.10)

Status in “gcc-4.9” package in Ubuntu:
  Fix Released
Status in “glibc” package in Ubuntu:
  New

Bug description:
  this can be reproduced in a 14.10 chroot, with -proposed enabled.

  link failure when the okteta package is built with -O3 (14.10), it
  succeeds when built with -O2.

  https://launchpad.net/ubuntu/+source/okteta/4:4.13.97-0ubuntu1
  search for "error:" in the build log. There is no error message from the linker.

  looking at the history of build failures this seems to be seen first
  with GCC 4.9 as the default GCC..

  workaround with -O2:
