Details:

File src/core/timers.c contain uninitialized pointer next_timeout. LWIP crash
on startup when memory is not initialized to zeroes.

Fix is simple like this:
..........
  /** Initialize this module */
  void sys_timeouts_init(void)
  {
+   next_timeout = NULL;
  #if IP_REASSEMBLY
..........
