[Pw_forum] SCF output information when testing espresso4.0cvs3

Hi, good morning,
I tested "espresso4.0cvs3" with a simple scf calculation.
I think the information for atomic magnetization in the output aren't 
reliable.
I tried to find where the problem is from but failed. 
Could you give me some opinions about it?
Thanks.

The input is as following:
----------------------------------------
  &control
     calculation='scf', pseudo_dir = '$pseudi', outdir='$workdir',
     prefix='bmo_4.2', disk_io='high', verbosity='high',/

     degauss=0.01, starting_magnetization(2)=1.0,
     constrained_magnetization='atomic',
     lambda=1.0, nspin=2,
  &electrons
     conv_thr =  1.0d-2

The output which only the atomic magnetization from the last 
scf step are shown. Notice the No.4 is zero.
