hostapd-2.3 using wired driver, crashes right after start

[Jan Humme]

I am trying to get hostapd-2.3 to run on my desktop computer, using the 
wired driver on a virtual ethernet port.

So I have downloaded and untarred hostapd-2.3.tar.gz, and adjusted the 
.config settings as follows:
> $ diff defconfig .config
> 13c13
> < CONFIG_DRIVER_HOSTAP=y
> ---
> > #CONFIG_DRIVER_HOSTAP=y
> 16c16
> < #CONFIG_DRIVER_WIRED=y
> ---
> > CONFIG_DRIVER_WIRED=y
> 23c23
> < CONFIG_DRIVER_NL80211=y
> ---
> > #CONFIG_DRIVER_NL80211=y


However hostapd seems to crash right after it starts up, not leaving 
much of a clue:

> $ sudo ./hostapd -dd hostapd.conf
> random: Trying to read entropy from /dev/random
> Configuration file: hostapd.conf
> ctrl_interface_group=0
> Opening raw packet socket for ifindex 9

Running hostapd in gdb gives:
> Program received signal SIGSEGV, Segmentation fault.

Here is my hostapd.conf:
> $ diff hostapd.conf.orig hostapd.conf
> 6c6,7
> < interface=wlan0
> ---
> > #interface=wlan0
> > interface=sta3
> 25a27

Anyone any ideas what might be wrong?

Thanks and best regards!
