> At 2 places the Type1Parser has a loop with a negated condition on the next
> token to be read. The loops simply advances to the next token without
> checking the token to be null, which may happen if the font is
> corrupted/shortened. If this occurs the parser is stuck in the loops. This
> happens to me for one of the loops with a file which however cannot be
> shared. The 2nd loop was found by scanning the code for similar problems.
