Debian 7 sendfromto()

[r00tk1d at km.pl.ua]

Hi!

I'm using Debian 7 (Linux bill0 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux)
and got the problem with Freeradius DHCP from current git. It's doesn't sent DHCP response
back to user, and, while debugging it, i found that by default Freeradius sets a WITH_UDPFROMTO
and thus uses udpfromto() function, but it always returns errno 22 (Invalid argument).
But when use --with-udpfromto=no for configure, there's no any problem. Is it expected behavior?
I'm using these parameters
./configure --with-static-modules=perl --with-dhcp --with-system-libtool --with-system-libpcre
for
