Memory alignment for strings ifort vs gfortran

So from what I gather, the “clean” solution seems to be to pass the length to FREE_STRINGand declare the`f_pointer`` as an assumed length character variable like:

It’s probably better. Just a detail, you have to account for the extra null char somewhere, either
f_free_string(c_string, strlen(c_string)+1);
or
CHARACTER(len=len+1), POINTER :: f_string

Also, you should use the kind=c_char for the declaration of what is passed to/from C.
