Looks like the programmer needs a few 'if (present(a)) then ... endif' block.
The code may be violating
F2023: 15.5.2.13 Argument presence and restrictions on arguments not present
...
An optional dummy argument that is not present is subject to the following
restrictions.
(1) If it is a data object, it shall not be referenced or be defined. ...
...
(4) It shall not be supplied as an actual argument corresponding to a
nonoptional dummy argument other than as the argument of the
intrinsic function PRESENT or as an argument of a function
reference that is a constant expression.
