[Pw_forum] Error: array gk out-of-bounds With ph.x

[dt331 at bath.ac.uk]

Dear All,

I am trying to run a phonon calculation by splitting the irreducible  
representations into a set of images. But I am receiving the errors:
     task #       621
      from gk_sort : error #         1
      array gk out-of-bounds

I ran the code with:
mpirun -n $NPROC -N $NTASK ph.x -nimage 4 -npool 10 < ${seed}.in > ${seed}.out

The error disappears if I do not use -nimage. Also it runs fine with  
-nimage in QE 4.3, but not with QE 5.0.

Does anyone know the source of the error?

Thanks,
David.
