If you want an official response you might rather ask on the developers list. I

It depends on what your generated parser is capable to do. That's the point of
the exception. It's an either or:
If your generated parser is *not* capable to generate yet another parser, then
yes, you could distribute the generated file under any license you wish and
hence you could do anything with it.
However if your generated parser is *capable* to generate another parser then
no, in that case the GPL automatically applies to your generated parser file as
well. Note that the pure potential of your generated parser to be capable of
generating another parser would be sufficient for the GPL to apply!
