Hello folks!
The bug discovered is in wav_player.c: when you invoke pjmedia_wav_player_port_get_pos() right after player has created (the position is 0)
or when no loop is specified and player already reached EOF and stopped (the position is again 0) - division by zero occurs.
Here is the patch proposed to address this small problem.
