> The DRL given below compiled in 5.1.1 and executed as expected, i.e., both rules fired, producing 
>    or R=1x2
>    and R=1x2
> Now, a syntax error is flagged at the position of the 2nd binding ($w:). Moreover, the DRL parser is thrown off-track and crashes with sn EmptyStackException as soon as more rules follow.
