It seems that there is something wrong in the reference counting for
namespaces, especially (only?) for the formal_ns of procedures. This was
noticed when working on PR 40877 (memory leaks with gfc_charlen). E.g. in
bounds_check_strlen_8.f90, the formal_ns of 'F1' is never freed up.
Reduced example:
FUNCTION F1(a,b,c,d) RESULT(RES)
CHARACTER(LEN=80), OPTIONAL :: a,b,c,d
LOGICAL :: res
END FUNCTION F1
When compiling this, gfc_free_namespace is called just once for the formal_ns
of 'F1', but ns->refs is 3, so it is never freed.
