fortran portion of test case

First part of a two part test case, Fortran & C.

The bug appears as: malloc: *** error for object 0x7fff695a8eb8: pointer be=
ing
freed was not allocated

The problem is observed in gcc/gfortran 9.3.0 and 10.2.0

If the intent of "array" is changed from "out" to "inout" the program runs
without any problem.=
