xlf 14.1:
"pr59720a.f90", line 20.4: 1514-699 (S) Procedure "s6b" must have a nonoptional
dummy argument that corresponds by position in the argument list to a dummy
argument not present in procedure "s6a", present and type incompatible, present
with different kind type parameters, or present with a different rank.

NAG Fortran Compiler Release 5.3.2(951)
Error: pr59720a.f90, line 40: Ambiguous specific names S6B and S6A in generic
BAD6
Errors in declarations, no further processing for FRUITS

pgfortran 13.10 accepts it.
