--- Comment #2 from Kempke, Nils-Christian <nils-christian.kempke at intel =

I forgot to mention that also for gfortran the bugfix did something:

I can now do

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Breakpoint 1, mvce () at ./f.f90:17
17        print*, foo, bar
(gdb) p foo
$1 =3D ( my_int =3D 0 )
(gdb) p bar
$2 =3D ( my_type =3D ( my_int =3D 1 ) )
(gdb) p bar%my_int
There is no member named my_int.
(gdb) p bar%my_type
$3 =3D ( my_int =3D 1 )
(gdb) p bar%my_type%my_int
$4 =3D 1
(gdb)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Note, that since the inheritance info is missing GDB has no way of knowing =
that
"p bar%my_int" is legal and one has to go the way via accessing the member
variable first.
