Extended Description

source code to reproduce fault
This one is very old apparently, but it's getting in my way today.
We have something like this:
 vec = [ m, n];
 vec2 =  _idx_modarray_AxSxS_( vec, 0, q);
 cols = _idx_sel_( 1, vec2);
This could be simplified to:
 cols = n;
The circumstances are that the two idx() indices 
are constant and NOT the same, and PRF_ARG1 of the modarray is 
a structural constant. In that case, we treat the expression
as if we had been given:
 cols = _idx_sel_( 1, vec);
This is already handled by CF.
