Extended Description

The attached example kills sac2c with one of those grumpy, incomprehensible
messages about types.
If you look at the computation of shpz in bslBBB, you'll see an expression
along the lines of:
 z=genarray (shape(x)++drop([1],shape(y)), false);
If you replace this with:
 shpz = shape(y);
 shpz[0] = shape(x)[0];
 z = genarray(shpz,false);
that works. I don't understand why one approach works and the other does not.
