  Hi All,

  I am using wpa_supplicant-0.5.11. I configured D-Link AP with WPA2-PSK and Cipher Type as "Auto". Getting seg fault. Please see logs below.
  In scan result it displayed following info.

    00:15:e9:ba:f3:66       2        188     [WPA2-PSK-TKIP+CCMP-preauth]    default

    I have following wpa_supplicant.conf file.

  # cat wpa_supplicant.conf.tmp 
  ctrl_interface=/var/run/wpa_supplicant
  ap_scan=2


  network={
                  ssid="default"
                  proto=WPA RSN
                  key_mgmt=WPA-PSK
                  pairwise=TKIP CCMP
                  group=TKIP CCMP
                  psk="testtest"
  }
