just found this on the GCC thread:

This bug was fixed in the package gcc-4.8 - 4.8.5-4ubuntu8

---------------
gcc-4.8 (4.8.5-4ubuntu8) bionic; urgency=medium

  [ Matthias Klose ]
  * Stop build gcj in current distro releases. Addresses: #892536.
  * Split off the documentation part from the retpoline patches.
  * Fix build dependency on realpath.

  [ Steve Beattie ]
  * Add retpoline support for x86 via adding -mindirect-branch=,
    -mindirect-branch-register, and -mfunction-return= support
    (LP: #1749261)

I've seen that the fix is currently only released for bionic.
What is the release date for trusty (gcc-4.8.5 Ubuntu 4.8.5-2ubuntu1~14.04.1) ?

Title:
  4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and
  16.04) due to outdated gcc-4.8

Status in gcc-4.8 package in Ubuntu:
  Fix Released

Bug description:
  Running fine with nvidia-384 until this kernel update came along.
  When booted into the new kernel, got super low resolution and nvidia-
  settings was missing most of its functionality - could not change
  resolution.

  Rebooted into 4.4.0-112 kernel and all was well.

  The root cause of the problem has been found to be installing the -116
  kernel without a sufficiently updated version of gcc.  In my case, my
  system received the gcc update AFTER the kernel update.

  Uninstalling the -116 kernel and reinstalling it with the updated
  version of gcc solved the problem for me.
