This looks like a threading issue. The examples from STM are horribly wrong in that respect. Read the docs at http://www.nongnu.org/lwip/ to learn about threading. Also, try upgrading to fit master and use the new LWIP_ASSERT_CORE_LOCKED() check (has to be implemented for your arch, look at our Freertos port for an example).
