【22.03 LTS SP2】【UDP】当客户端发送包长和服务端配置的包长不一致时会发生coredump

【标题描述】当客户端发送包长大于服务端配置的包长时会发生coredump
【环境信息】
硬件信息：
1）裸机场景提供出问题的硬件信息；
2）虚机场景提供虚机XML文件或者配置信息
软件信息：
1） OS版本及分支
2）内核信息
3）发现问题的组件版本信息
两台虚拟机
[root@openEuler gazelle]# cat /etc/openEuler-latest
openeulerversion=openEuler-22.03-LTS-SP2

【问题复现步骤】
客户端LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=example ./example -D udp -a client -i 124.88.104.76 -p 12345 -A recvfromsendto -P 513
服务端 LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=example ./example -D udp -a server -i 124.88.104.76 -p 12345 -A recvfromsendto -P 512

【预期结果】
可以正常打流

【实际结果】
客户端发生coredump
