implicit none
integer :: fx1(10)=1
integer :: fx2(20)=2
integer,allocatable :: a(:)
a=-fx1
! I would expect errors like "different shape for array assignment" where
indicated?
a(:)=[fx2+1];       call show('B')  !! NO ERROR?
a=-1
a(:10)=[fx2*2,fx1]; call show('C')  !! NO ERROR?
a=-2
a(:)=[fx2,fx1];     call show('D')  !! NO ERROR?
contains
subroutine show(prefix)
character(len=*),intent(in) :: prefix
   write(*,'(a,":",*(i0,1x))')prefix,size(a),a
end subroutine show
end

B:10 3 3 3 3 3 3 3 3 3 3
C:10 4 4 4 4 4 4 4 4 4 4
D:10 2 2 2 2 2 2 2 2 2 2
