OK for mainline, 4.2 and 4.1 with usual conditions. I think you're
missing a ChangeLog bit for the following:

*************** ok:
*** 2384,2390 ****
       break;
     }

!   gfc_error ("Syntax error in data declaration at %C");
   m = MATCH_ERROR;

   gfc_free_data_all (gfc_current_ns);
--- 2385,2392 ----
       break;
     }

!   if (gfc_error_flag_test () == 0)
!     gfc_error ("Syntax error in data declaration at %C");
   m = MATCH_ERROR;

   gfc_free_data_all (gfc_current_ns);
