NLTK: Uncontrolled resource consumption in RecursiveDescentParser via ambiguous or left-recursive grammars
`nltk.parse.RecursiveDescentParser` (and `SteppingRecursiveDescentParser`) enumerate parses top-down with no bound on the number of recursive steps. A small, crafted context-free grammar makes a short input consume unbounded CPU (and/or exhaust the Python rec…
