This comes up most times Fortran is mentioned, but it is not true that Fortran passes by reference, and optimizations rely on that fact. The rules around storage association are typically referred to as pass by value-return or copy-in/copy-out. It's misleading to imply you never have to free memory. The NAG compiler runtime includes Boehm's conservative garbage collector (or did, last I checked) for a reason.
