Hi,

i'm trying to get latest CVS rtpproxy running. Unfortunately, it tends
to crash as soon as the second leg of a call is established (200 OK, sipwise):

(gdb) file /usr/bin/rtpproxy
Reading symbols from /usr/bin/rtpproxy...done.
(gdb) run -f
Starting program: /usr/bin/rtpproxy -f
rtpproxy: rtpproxy started, pid 9031

tag 3143037586 requested
rtpproxy: new session on a port 35000 created, tag 3143037586

    sa_family_t sa_family;
    char sa_data[14];
} *
(gdb) print ia1->sa_data

ia2 looks fine, btw.

I have no idea what should happen at main.c:760, looks like something
related to the ip4<->ip6 conversion/bridging... 

anyone who can either enlighten me, or (preferred ;) even fix that bug?

maxim? ;)

cheers
