Among the errors I see with coarray_shared are
FAIL: gfortran.dg/coarray.sh/team_change_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (internal compiler error)
FAIL: gfortran.dg/coarray.sh/team_change_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (test for excess errors)
FAIL: gfortran.dg/coarray.sh/team_end_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (internal compiler error)
FAIL: gfortran.dg/coarray.sh/team_end_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (test for excess errors)
FAIL: gfortran.dg/coarray.sh/team_number_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (internal compiler error)
FAIL: gfortran.dg/coarray.sh/team_number_1.f90 -fcoarray=shared -O2
-lcaf_shared -latomic (test for excess errors)
The failures are:
internal compiler error: in conv_intrinsic_team_number, at
fortran/trans-intrinsic.c:2677
which is
gcc_unreachable ();
I think there ere missing if blocks for GFC_FCOARRAY_SHARED. For them
should we use gfor_fndecl_caf_team_number or anything else?
Cheers,
Dominique

Teams are not yet implemented, this is known :-) and documented
under libgfortran/caf_shared/README.native_coarrays.
In general, we try to have all test cases known to succeed in
the gfortran.dg/caf-shared directory.

I haven't looked at teams too closely yet. We will need a few decls in
the front end. These should be separate from the caf_ names because
the number and types of arguments might be different, and we don't want
to pick up the wrong ones. All decls for shared memory coarrays have
cas instead of caf in their names.
Also, teams need to be implemented on the library side as well.
Best regards
Thomas
