The following reduced code does not give the expected error: subroutine lock_test2 use iso_fortran_env implicit none type t end type t type(t) :: x type(lock_type), save :: lock[*],lock2(2)[*] lock(lock) lock(lock2(1)) lock(lock[1]) ! { dg-error "must be a scalar coarray of type LOCK_TYPE" } ! <-- no error end subroutine lock_test2
