[Pw_forum] pw2wannier90: compute uHu crashes (example works fine)

[Christoph Wolf]

Dear all,

I recently tried computing orbital magnetization etc following example 19
of the wannier package; Works all great, however when I try to adapt this
for different systems pw2wannier90.x (from pwscf 6.0, 6.1 and 6.2) crashes
when attempting to calculate uHu.

 iknum =      512

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

Since the example works fine (with pseudos from pslibrary 1.0.0 in
LDA/Normcons.) I suspect something else to be the problem (I tried to
calculate SrVO3); I am a bit lost finding the problem so any hint is very
much appreciated!

pseudos were generated as below:

<PP_INPUTFILE>
 &input
   title='Sr',
   zed=38.,
   rel=2,
   config='[Kr] 5s2.0 5p0.0 4d0.0',
   iswitch=3,
   dft='LDA'
 /
 &inputp
   pseudotype=2,
   file_pseudopw='Sr-rel.LDA-n-nc.UPF',
   author='TM',
   lloc=0,
   nlcc=.true.,
   tm=.true.
 /
3
5P  2  1  0.00  0.00  3.80  3.80  0.0
4D  3  2  0.00  0.00  3.60  3.60  0.0
5S  1  0  2.00  0.00  3.60  3.60  0.0


Interpolated bands look great (compared to A. Scaramucci ArXiv:1405.3804v1)
and wannierization has no problems...

TIA for any help!

Best,
Chris
