re PR fortran/46060 ([F03] procedure pointer component referenced without argument list)
2010-10-21 Janus Weil <janus@gcc.gnu.org> PR fortran/46060 * match.h (gfc_matching_ptr_assignment): New global variable to indicate we're currently matching a (non-proc-)pointer assignment. * decl.c (match_pointer_init): Set it. * match.c (gfc_match_pointer_assignment): Ditto. * primary.c (matching_actual_arglist): New global variable to indicate we're currently matching an actual argument list. (gfc_match_actual_arglist): Set it. (gfc_match_varspec): Reject procedure pointer component calls with missing argument list. 2010-10-21 Janus Weil <janus@gcc.gnu.org> PR fortran/46060 * gfortran.dg/proc_ptr_comp_25.f90: New.
