wpa_supplicant segmentation fault

[Cristian NAVALICI]

Hello,

I'm struggling to get up an wireless card (EDIMAX PCI adapter based on
Ralink RT2561/RT61 802.11g chipset). I managed to install the card
drivers, everything seems to be ok.

# iwconfig
lo        no wireless extensions.

I tried then to use wpa_supplicant for WAP encryption with my wireless
router, but when I tried to start up wpa_supplicant I got a nasty
segmentation fault error.

This wpa_supplicant is built from the sources, but I tried either with
packages.
I run Centos 5.2 64bit version.

As a curiosity, on the same computer, but with Centos 5 32bit version,
this seems to work without any problem. So I guess it's related to 64bit
architecture.

Anyone can help?
Thanks in advance.
