Re: compiler bug?

[Jose E. Marchesi]

Hi John.

    Loading this Poke program:
    
    deftype xxx = struct
    {
      char[2] c;
    };
    
    defun sum = (offset<int, xxx> input) void:
    {
      defvar h = xxx @ input + 0#xxx;
    }
    
    
    causes poke to assert with:
    
    /home/john/SRC/poke/src/pkl-typify.c:515: pkl_typify1_ps_add:
    Assertion `PKL_AST_CODE (unit_type_2) == PKL_AST_INTEGER' failed.

Yes, that's a compiler bug.  I have a branch on progress with fixes
related to offsets, that should fix this as well.
