[Bug fortran/23905] misbehavior of function "gfc_copy_array_spec" in gcc/fortran/array.c

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I believe the gfc_copy_array_spec() function is correct. Its purpose is to
allocate memory for the dest gfc_array_spec. It then copies all fields of src
into dest (Steve: copying pointers would be "dest = src", but "*dest = *src"
really copies the contents of the gfc_array_spec).

After that, the loop is used to create copies of lower and upper fields. Since
these fields were copied from src into dest in the last step ("*dest = *src"),

dest->lower[i] = gfc_copy_expr (dest->lower[i]);

is really equivalent to

dest->lower[i] = gfc_copy_expr (src->lower[i]);


Closing this PR accordingly. If I missed something, please feel free to reopen.
