This was down to me, netif -> state was pointing to something that was created on the stack and which no longer existed! Having resolved that, it appears that it is getting a bit further but the call to tcp_connect() fails and eventually the error callback is triggered with ERR_ABRT. Having poked around under the hood in tcp.c the failure is triggered as a result of "max SYN retries" being reached. I have tried simple things like increasing the value of TCP_SYNMAXRTX but it is obviously a more subtle issue than that.
