pyferret fails on startup

[henkela]

Hi,
I've built pyferret 7.6.3 on a CentOS 8 system using GCC 11.2.0, OpenMPI 4.1.1, NetCDF 4.8.1, NetCDF-fortran 4.5.3, Python 3.9.6, numpy 1.12.3,scipy 1.7.1.
For a successful build I needed to add --fallow-invalid-boz and -fallow-argument-mismatch for FFLAGS and PPLUS_FFLAGS in platform_specific.mk.x86_64-linux as well as external_functions/ef_utility/platform_specific.mk.x86_64-linux.

After the install I set up everything using bin/Finstall and went ahead to tried the optional test of installation by calling sourcing the ferret_paths.sh an starting pyferret -nodisplay. However, no matter which flag I use when I call pyferret -nodisplay it immediately exits with
**TMAP ERR:
MAX= 1000
STOP DFN_SPC_GRD

I see the same if I use GCC 8.3.0, Python 3.7.2, netCDF-Fortran 4.5.2.

Any ideas on that?
