    _______________________________________________________

Details:

Sys_sem_signal(op_completed_sem) crash in lwip_netconn_do_connected function
due to the op_completed_sem has been freed.

Because this crash is reproduced in customer product.
I don't know other more detailed info.

"What's the reason" or "how to call Socket API", maybe cause the crash issue.

Thanks
