f18 current emits an error when an assignment is made to an array section with a vector subscript, and the array is finalized with a non-elemental final subroutine. Some other compilers emit this error because (I think) they want variables to only be finalized in place, not by a subroutine call involving copy-in & copy-out of the finalized elements. Since many other Fortran compilers can handle this case, and there's nothing in the standards to preclude it, let's downgrade this error message to a portability warning. This patch got complicated because the API for the WhyNotDefinable() utility routine was such that it would return a message only in error cases, and there was no provision for returning non-fatal messages. It now returns either nothing, a fatal message, or a non-fatal warning message, and all of its call sites have been modified to cope.
