Java 版本进行jmeter压测程序退出

如题，在进行Java版本lac单线程分词时，出现:

> （1） *** Error in `java': double free or corruption (out): 0x00007f9e6c2cbf40 ***
>
> （2）terminate called after throwing an instance of 'std::bad_alloc'
> what(): std::bad_alloc
> Aborted
>

The report concerns the Java version of LAC during a JMeter load test using single-thread segmentation; start by reproducing the reported double-free and std::bad_alloc failures. Done means the exit is explained and a verified fix or clear reproduction boundary is documented.
