RTX with Flash File System

Good afternoon.
I try to start SD a card on LPC2378. Without RTX all perfectly works. With RTX on a command finit () the program jumps on DAbt_Addr. The theme (http://www.keil.com/forum/docs/thread15068.asp) at a forum has not helped.
My code:

int main()
{
  os_sys_init(init);
   while(1);
}

__task void init (void) {
   os_tsk_prio_self (100);
   finit();
   os_tsk_create_user (blink_led, 30, &blink_stack, sizeof(blink_stack));
   os_tsk_create (timer_task, 30);
   os_tsk_create_user (tcp_task, 0, &tcp_stack, sizeof(tcp_stack));
   os_tsk_delete_self();
}

Show working example RTX with functions Flash File System
