Fortran implementation based on gcc is faulty due to libgcc_s.so being 
present in 2 versions, in base and in gcc port, making any code 
containing both C++ and fortran impossible to run. Your application 
probably can't work on FreeBSD using gcc fortran for this reason.


You can try to apply the patch from 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220313 and then have 
USES=fortran:flang instead of just USES=fortran in your port. Please let 
me know if this works. flang is a new, experimental fortran 
implementation that aims to replace gcc fortran.
