I also get a lot of these warnings:

After I updated to lwip version 1.3.1, FreeRTOS can no longer start
the tcpip_thread.
Here's the gdb output:
Program received signal SIGINT, Interrupt.

The sys_thread_new in my sys_arch.c looks like this:
sys_thread_t sys_thread_new(char *name, void (* thread)(void *arg),
void *arg, int stacksize, int prio)
{
xTaskHandle CreatedTask;
int result;
result = xTaskCreate( thread, name, stacksize, arg, prio,
&CreatedTask );
.....
Which modifications in lwip 1.3.1 could be causing this?
Best regards
