This is almost impossible too... ppp_over_serial_open() set pcb->phase 
to PHASE_INITIALIZE (1) before starting PPP. pcb->phase can't be set to 
0 at this time.

int ppp_over_serial_open(...)
  [...]
  new_phase(pcb, PHASE_INITIALIZE);
  ppp_start(pcb);
  [...]
}

This is either a compiler bug, because ppp_pcb use compiler generated 
bitfield from struct, or a memory corruption.

You can check the first by replacing bitfield to u8_t type for each 
bitfield entry in all structures used by PPP.

Here is a sed regexp that, applied to all headers files, should do the job:
  s/^\(.*\)u_int\(.*\):[^1]*1[^;]*\(.*\)$/\1u8_t\2\3/
