Thanks!

Maybe somebody could eyeball and ACK "Fix memory leak in finalization
wrappers"
https://gcc.gnu.org/pipermail/fortran/2021-October/056838.html

We were generating (and emitting to modules) finalization wrapper
needlessly, i.e. even when they were not called for.

This 1) leaked like shown in the initial submission and
2) polluted module files with unwarranted (wrong) mention of
finalization wrappers even when compiling without any coarray stuff.

E.g. a modified udr10.f90 (from libgomp) has the following diff in the
module which illustrates the positive side-effect of the fix:

-26 'array' '' '' 25 ((VARIABLE INOUT UNKNOWN-PROC UNKNOWN UNKNOWN 0 0
-ARTIFICIAL DIMENSION CONTIGUOUS DUMMY) () (DERIVED 3 0 0 0 DERIVED ()) 0
-0 () (0 0 ASSUMED_RANK) 0 () () () 0 0)
-27 'byte_stride' '' '' 25 ((VARIABLE UNKNOWN-INTENT UNKNOWN-PROC UNKNOWN
-UNKNOWN 0 0 ARTIFICIAL VALUE DUMMY) () (INTEGER 8 0 0 0 INTEGER ()) 0 0
-() () 0 () () () 0 0)
-28 'fini_coarray' '' '' 25 ((VARIABLE UNKNOWN-INTENT UNKNOWN-PROC
-UNKNOWN UNKNOWN 0 0 ARTIFICIAL VALUE DUMMY) () (LOGICAL 1 0 0 0 LOGICAL
-()) 0 0 () () 0 () () () 0 0)

thanks,
