NetCDF4 segfault on file open

March 21, 2020

NetCDF4 Fortran library may compile successfully and run for simple programs but segfault on programs where HDF5 is linked directly as well as NetCDF4.

A reason one might directly link both HDF5 and NetCDF is a program that need to read / write files in HDF5 as well as NetCDF format. The symptom observe thus far is the program segfault on nf90_open().

The fix is to compile HDF5 and NetCDF for yourself.
