v1.2报错Segmentation fault

[demondfdfjg]

对应socket.cpp 1068-1082代码： // Someone added new requests.
// Reverse the list until old_head.
WriteRequest* tail = NULL;
WriteRequest* p = new_head;
do {
while (p->next == WriteRequest::UNCONNECTED) {
// TODO(gejun): elaborate this
sched_yield();
}
WriteRequest* const saved_next = p->next;
p->next = tail;
tail = p;
p = saved_next;
CHECK(p != NULL);
} while (p != old_head);
二进制程序依赖了mrpc，执行压测时候报错：received signal SIGSEGV, Segmentation fault.
