Сфинкс 4, поврежден ARPA LM?

У меня есть ARPA LM, сгенерированный kylm , при запуске SPHINX я получаю эту трассировку стека исключений: 

Exception in thread "main" java.lang.RuntimeException: Allocation of search manager resources failed

Вот выдержка из ARPA LM: 

[n]
3

[smoother]
kylm.model.ngram.smoother.KNSmoother

[closed]
true

[max_length]
1091

[vocab_cutoff]
0

[start_symbol]
<s>

[terminal_symbol]
</s>

[unknown_symbol]
<unk>

\data\
ngram 1=406
ngram 2=768
ngram 3=937
\1-grams: 
-99.0000    <s> -0.3630
...
...

\end\

PS : после \end\

появляется новая строка

Исключение говорит о том, что SPHINX сталкивается с неожиданным EOF в последней строке (разве он не должен там встречаться с EOF ??)

Пожалуйста, помогите!

Оказывается, это ошибка SPHINX 4.

Если директива \1-grams: (или любая другая директива на самом деле) содержала хвостовое пространство [s], SimpleNGramModel не удалось его проанализировать!Я только что представил патч, но вы можете найти его здесь .
