Extended Description

The following program dies in alloc.c when compiled with no options:
int main()
{
 v1 = id( [ 42]);
 gV, p2 = _non_neg_val_V_( v1);
 gS = _sel_VxA_( [0], gV);
 z = _sub_SxS_(gS , 42);
 return( z); 
}
int[*] id( int[*] y)
{
 return(y);
}

Failure mode:
** 16: Introducing memory management instructions ...
  **** Unshare index vectors in WL-folds ...
  **** Propagating constants ...
  **** AUD/SCL distinction ...
  **** Making copy operations explicit ...
  **** Introducing explicit allocation statements  ...
memory/alloc.c:308 Assertion "als->dim != NULL" failed!
alloc requires a dim expression!
If someone can tell me how to write an alloc.c thingy for
a function that has two results, I'll fix it.
