** Description changed:

  $ sudo snappy install ubuntu-clock-app.ubuntucore-dev
  $ ubuntu-clock-app.clock
  aa_change_onexec failed with -1. errmsg: Permission denied
  [1]
  
  Downgrading to ubuntu-core-launcher doesn't help the clock app get past
  this failure.
  
  The hello-world app works ok (it needs ubuntu-core-launcher 1.0.20 since it gets past the above error and the launcher needs to account for NO_NEW_PRIVS):
  $ hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0
  
  $ sudo /snaps/bin/hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0
  
  cap-test.mvo doesn't have this problem either:
  $ sudo snappy install cap-test.mvo
  $ cap-test.xbomb
  
  If I disable the apparmor profile with: sudo apparmor_parser -R
  /etc/apparmor.d/usr.bin.ubuntu-core-launcher then the app will launch.
+ 
+ Downgrading to the -13 kernel resolves the issue:
+ $ cat /proc/version_signature 
+ Ubuntu 4.4.0-13.29-generic 4.4.5
