[I] 求助：socket.cpp:1036, IsWriteComplete] Check failed: NULL == old_head->next (brpc)
zcfh opened a new issue, #2572:
URL: https://github.com/apache/brpc/issues/2572
Describe the bug (描述bug)
使用 clang-17 进行autofdo优化。 服务出现
F0314 16:33:23.030470 211226 socket.cpp:1071, IsWriteComplete] Check failed: p != NULL
*** Check failure stack trace: ***
F0314 16:33:23.035867 211251 socket.cpp:1036, IsWriteComplete] Check failed: NULL == old_head->next
*** Check failure stack trace: ***
core的调用栈是在
```
(gdb) bt
#0 0x0000000001e1a1e3 in brpc::Socket::KeepWrite(void*) (void_arg=<optimized out>) at third_party/brpc-0.9.6/src/brpc/socket.cpp:1629

#3 0x0000000000000000 in ?? ()
(gdb) p req
$1 = (struct WriteRequest *) 0xffffffffffffffff
```
简单看了下代码，没搞懂 IsWriteComplete 里 CHECK_NE(new_head, old_head); , new_head 和 old_head 是在哪里编成不同的的。
有没有排查思路？

参考 #2156 ，这个issue。
- 如果你的brpc版本比较低，可以升级解决。
- 如果你是升级编译器版本的过程中遇到，大概率是编译器默认使用 -pie 链接引起
