The calltrace as follow:
#0 0x0000000000000000 in ?? ()
#1 0x00007f7b04a20e6f in worker (arg=0x0) at src/threadpool.c:83
#2 0x00007f7b04238dc5 in start_thread () from /lib64/libpthread.so.0
#3 0x00007f7b0474c73d in clone () from /lib64/libc.so.6

Why the arg is null?

`
uv_loop_t *loop;
uv_work_t req;
loop=uv_default_loop();

while(1)
uv_queue_work(loop,&req,worker,after_worker);

uv_run(loop,UV_RUN_DEFAULT);
