Florian, where is this code? In an action? Driver code? Don't use the 
direct code like this as if I cahnge it, then all your code will break. 
There are macros, such as PARSER and so on that you should use. Look at 
the top of the generated code for more details.

If you use LT rather than LA, then you will get a token pointer and it 
has pointers to the input stream where the token starts and a length field.
