Here we go:

% xlf2008 pr59720.f90
** kleiner   === End of Compilation 1 ===
"pr59720.f90", line 42.44: 1514-699 (S) Procedure "ass_gf" must have a
nonoptional dummy argument that corresponds by position in the argument list to
a dummy argument not present in procedure "ass_en", present and type
incompatible, present with different kind type parameters, or present with a
different rank.

% nagfor pr59720.f90
NAG Fortran Compiler Release 5.3.2(951)
Error: pr59720.f90, line 65: Ambiguous specific type-bound procedures ASSIGN2
and ASSIGN for type-bound generic ASSIGNMENT(=) in type MYTYPE
Errors in declarations, no further processing for GROSSER


Apparently both agree with gfortran ;-)
