Usually that's a strong indication about ABI breakage in a library.

I know nothing about Fortran ABI rules, but nf90_def_var_oneDim() 
gaining 3 (optional) parameters in 4.6.0 is suspiciously close
to #3 in the backtrace.

Please check with upstream whether a soname bump might be necessary
for libnetcdff.
