[lwip-users] crash after update from lwip 1.3.0 to 1.3.1 under FreeRTOS 5.4.2

[Jesper Vestergaard]

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.
0x00013a08 in _handle_Bus_Error_Data_Fetch ()
(gdb) bt
#0  0x00013a08 in _handle_Bus_Error_Data_Fetch ()

   pxCreatedTask=0x24007fbc) at FreeRTOS/tasks.c:453

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?
