wpa_supplicant crashes under Windows XP

Hello,

I have an application that launches wpa_supplicant via the windows
create process api. In this application wap_supplicant connects to
various wpa-psk networks, sometimes tkip, sometimes AES, and sometimes
this IEEE D9/WPA2 flavor of WPA-PSK.

I have found that wpa_supplicant will usually crash after one to three
hours of operation.  

The computer is a Dell Optiplex running Windows XP. This crash happens
with several different adapters and access points.  Apparently the crash
happens after an uncommanded disassociation from the desired access
point.

Typical console output prior to the crash is:

RSN: PMKID candidate event - bssid=00:d0:59:e1:01:94 index=9 preauth=0

State: COMPLETED -> ASSOCIATED
Associated to a new BSS: BSSID=00:00:00:00:00:00

Note that wpa_supplicant thinks it has associated with a BSSID value of
all zeros.

Is it possible that this all zero bssid is causing my crashes?

Thanks
