使用dwp查看clang编译出来的文件，会导致dwp产生coredump。
clang的版本:
[root@RH8-LCP ~]# strings envoy | grep -i clang | more
Ubuntu clang version 14.0.0-1ubuntu1.1
Ubuntu clang version 14.0.0-1ubuntu1.1

coredump信息，从调用栈可以看到传递到fseek的fp是空，这也是coredump的原因：
[Thread debugging using libthread_db enabled]

Core was generated by `dwp -e envoy’.
