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"
}
