IEEE 802.1x with dynamic WEP doesn't work in hostapd CVS

[Andrew Barr]

I upgraded my AP to the latest HostAP CVS trying to resolve a WPA issue that 
now appears to be the fault of the driver (or operator) ;-). Failing to 
resolve the issue, I configured my AP to use IEEE 802.1x with dynamic WEP, 
and I could not authenticate. Running xsupplicant with -d9 for verbose 
debugging, I got this:

tigris abarr # xsupplicant -i eth1 -f -d9

Notice the invalid EAPOL frame message. Downgrading to the latest release 
(hostapd 0.2.5) immediately resolves the problem. Does the CVS version of 
hostapd work, or should I be sticking to stable releases here?
