Dear all,
So far I never tried lapw5.
Now, at my first tries I rceived a problem in lapw 5.
It appears in line 16 of charg.f (or line 18 in the charg.f coming with the ncm version)
      IR=1+LOG(R/RNOT(JATOM))/DX(JATOM)
for the first call at JATOM=1
Converting the second part of 1 + ... into integer did not help.
It also seems all fields are allocated correctly.
(in the ncm version it was a segmentation fault, no special message in the regular version
the vesions are nearly identical besides some small formatings of the fortran file)

For the regular version (not ncm) I used for the simple case of Fe the case.in5 with
 0 0 0 1           # origin of plot: x,y,z,denominator
 1 0 0 1           # x-end of plot
 0 1 0 1           # y-end of plot
 2 2 2             # x,y,z nshells (of unit cells)
 100 100           # nx,ny
 RHO               # RHO/DIFF/OVER; ADD/SUB or blank, A4 format
 ANG VAL NODEBUG   # ANG/ATU, VAL/TOT, DEBUG/NODEBUG

and similar for some more complicated collinear and non-collinear cases.

Compiler was ifort from OneAPI 24.1

Did someone else observe something similar or/and has a solution 

Ciao
Gerhard
