I believe gfortran's behavior conforms to the standard. F2003 states
When the execution of a procedure is terminated by execution
of a RETURN or END statement, an allocatable variable that is
a named local variable of the procedure retains its allocation
and definition status if it has the SAVE attribute or is a
function result variable or a subobject thereof; otherwise, it
is deallocated.
val is a local variable. val does not have the SAVE attribute.
