Sphinx 4 corrupted ARPA LM?

I have an ARPA LM generated by kylm, when running SPHINX I get this exception stack trace:

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

Here's an excerpt of the ARPA LM:

[n]

[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: there is a new line after \end\

The exeption 开发者_如何学编程says that SPHINX is encountering an unexpected EOF on the last line (isn't it supposed to encounter an EOF there ??)

Please any help !

It turns out to be a SPHINX 4 bug.

If the \1-grams: directive (or any other directive actually) contained tailing space[s], SimpleNGramModel failed to parse it ! I just submitted the patch, but you can find it here.
