Deleting the dimension from parameter a (making it scalar)
lets examples z1.f90 and z5.f90 compile and run fine.


$ cat y1.f90
program p
   block
  real, parameter :: a = 1.0
  real :: x(2)
  x = a
  print *, x
  block
 print *, x
  end block
  print *, x
   end block
end

$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize y1.f90
$ a.out
   1.   1.
   1.   1.
   1.   1.

$ cat y5.f90
program p
   block
  real, parameter :: a = 1.0
  real :: x(2)
  x = a
  print *, x
   end block
end

$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize y5.f90
$ a.out
   1.   1.

The a(2) appears to be optimized out.  Don't know if the
code is legal because I haven't looked at standard, yet.
Changing your print statement to 

  if (x(1) /= 1.0) call abort

gives

% gfc6 -fdump-tree-original -c g5.f90
% cat g5.f90.003t.original
p ()
{
  {
real(kind=4) x[2];

(void) __builtin_memcpy ((void *) , (void *) , 8);
if (x[0] != 1.0e+0)
  {
_gfortran_abort ();
  }
L.2:;
L.1:;
  }
}
