在Linux系统上用Java单线程批量做分词报错，terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

在Linux系统上用Java单线程批量做分词报错，大概处理了四十多万调数据之后报如下错误，并造成程序直接退出
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
请问这个问题什么原因导致的？

Reproduce the Linux Java single-threaded batch segmentation run described in the issue, continuing beyond 400,000 records while capturing the native std::bad_alloc failure. Start by tracing the Java-to-native segmentation path and memory usage; done means identifying the failure cause and documenting a verified fix or limitation.
