The same error occurs for the test case in PR 49112 comment 7:


module datetime_mod

    implicit none
    private

    type :: DateTime
    contains
        procedure :: getFormattedString
    end type

contains

    function getTimeString(dt, FMT) result(string)
        character(:), allocatable :: string
        class(DateTime), intent(IN) :: dt
        integer, optional, intent(IN) :: FMT

        string = dt%getFormattedString(2, FMT)
    end function 

    function getFormattedString(this, FILTER, FMT) &
        result(string)
        character(:), allocatable :: string
        class(DateTime), intent(IN) :: this
        integer, optional, intent(IN) :: FILTER, FMT

    end function

end module
