There's one known leak in the parser that occurs when the parser hits a
syntax error. In that case the bison generated will unwind and leave the
memory allocated for string tokens without an owner. Last time I tried to
solve it I realized how difficult it is to do with bison. Having a pool of
strings allocated during parsing (that could be freed in the end if they
are unused might be a possibility).
