[Wannier] Error when using pw2wannier90.x

[Giovanni Pizzi]

Dear Pang Rui,
did you check that you are running pw2wannier90.x with the same number of CPUs (and same parallelization options) of the pw.x code?
In case, you can also try to re-run pw.x with the wf_collect flag set to True to see if things change.

Best,
Giovanni Pizzi

    Parallel version (MPI), running on    48 processors
    R & G space division:  proc/nbgrp/npool/nimage =      48
and show message like
mpirun noticed that process rank 0 with PID 41687 on node fn002 exited on
signal 11 (Segmentation fault)
I do not think it is because insufficient memory because the pwscf.save is
only 4M. Did anyone meet this problem before?

The following is the input file
&inputpp
  outdir = './'
  seedname = 'ni_down'
  spin_component = 'down'
  write_mmn = .true.
  write_amn = .true.
