gfortran 13.0.0 20220925 snapshot (g:77bbf69d2981dafc2ef3e59bfbefb645d88bab9d)
ICEs when compiling the following testcase w/ -fchecking, reduced from
test/Lower/forall/array-pointer.f90 from the flang 15.0.1 test suite:
module array_of_pointer_test
type ta
integer, POINTER :: ip(:)
end type ta
type tb
integer, POINTER :: ip(:,:)
end type tb
end module array_of_pointer_test
subroutine s5(y,z,n1,n2)
use array_of_pointer_test
type(tb) :: y(:)
type(ta), TARGET :: z(:)
forall (i=1:10)
y(i)%ip(1:n1,1:n2) => z(i)%ip
end forall
end subroutine s5
