I'm not able to reproduce the issue locally with the Intel 19.0.5 compilers, which is the closest version that I have access to. Could you try compiling and running the attached test program, which is based on the relevant code for reading the namelist.wps file in the geogrid program? You could initially just try compiling with
ifort namelist_test.f90 -o namelist_test
then run the 'namelist_test' program from within your WPS working directory.

Interestingly, there is a similar sort of error that has been reported in the MPAS-Atmosphere model in this post: .
