It works for me. The following two variants give the correct result (and this
is without any patching):

program main
 use test
 implicit none
 type(a), target :: myA
 integer, dimension(:), pointer :: ptr
 myA%i(1:4)%j = (/ 1, 2, 3, 4 /)
 myA%i(1:4)%c = (/ 'a', 'b', 'c', 'd' /)
 allocate (ptr(4))
 ptr =  myA%i%j
 print *, "       ptr =", ptr
 print *, "   myA%i%j =", myA%i%j
end program main

program main
 use test
 implicit none
 type(a), target :: myA
 integer, dimension(:), pointer :: ptr
 myA%i(1:4)%j = (/ 1, 2, 3, 4 /)
 myA%i(1:4)%c = (/ 'a', 'b', 'c', 'd' /)
 ptr => myA%i%j
 print *, "       ptr =", ptr
 print *, "   myA%i%j =", myA%i%j
end program main


Both give:
        ptr =           1           2           3           4
    myA%i%j =           1           2           3           4
