Invalid opcode on client registration in ADC master role

System Information:
  Description: Ubuntu Trusty Tahr (development branch)
  Release: 14.04

Package version:
  samba4: 4.0.3+dfsg1-0.1ubuntu4
  samba: 2:4.1.3+dfsg-2ubuntu3

What did I expect to happen:
  Client auto-registration when running samba as active directory master works

What happened instead:
  Client could not register (active directory master could not perform operation)

Additional information:
  /var/log/messages contains information about a trap
  kernel: [ 155.531461] traps: samba[956] trap invalid opcode ip:7f55b1e328de sp:7fff834b9c38 error:0 in libHDB_SAMBA4.so.0[7f55b1e31000+2000]

Remedy:
  As a solution I downloaded the newer 2:4.1.5+dfsg-1 from https://packages.debian.org/sid/samba and compiled from source. The bug did not occur, clients were successfully able to register
