Extended Description

Build #16697 fails to perform WLS on this code (and many others):
int main()
{
  A = with  {
    (. <= iv=[i] <= .) {
     B = with {
       (. <= jv=[j] <= .) {
         VAL = _add_SxS_( i, _mul_SxS_( 2, j));
       } : VAL;
      } : genarray([4], 42);
    } : B;
   } : genarray([4], [10,20,30,40]);
  StdIO::print(A);
  return(0);
}
sac2c -d#,WLS gives this:
with {
      (_flat_2 <= iv=[i] < _flat_5 genwidth [ _wlsimp_115 ])
      {
        B = with {
              (_flat_2 <= jv=[j] < _flat_5 genwidth [ _wlsimp_116 ])
              {
                _flat_12 = _mul_SxS_( _flat_13, j);
                VAL = _add_SxS_( i, _flat_12);
              } : VAL ;
 } :
            genarray( _flat_5, _flat_7);
      } : B ;
 } :
    genarray( _flat_5, _flat_1)
-----------------------------------------------
 WLSCdoCheck: WLS: A: Checking whether with-loop can be scalarized.
    WLSCwith: WLS: A: Outer with-loop has no full partition
 WLSCdoCheck: WLS: A: With-loop cannot be scalarized.
I'm looking into it now, to see if there's a simple fix.
