I just built new sip router and at startup it is still crashing:

Oct  5 09:54:44 sip /usr/sbin/sip-proxy[12757]: ERROR: <core> [udp_server.c:401]: ERROR: udp_init: bind(9, 0xb7229fa0, 16) on 192.98.102.10: Cannot assign requested address
Oct  5 09:54:44 sip kernel: [67602.220819] sip-proxy[12757]: segfault at 786e6570 ip b7693e38 sp bfc5242c error 4 in libc-2.11.2.so[b7621000+140000]

i had sr running with this kind of interface configuration:

eth0      Link encap:Ethernet  HWaddr 00:26:18:92:69:72  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          Interrupt:24

          Interrupt:24

          inet addr:127.0.0.1  Mask:255.0.0.0

ppp0      Link encap:Point-to-Point Protocol  
          inet addr:87.93.95.247  P-t-P:10.0.0.1  Mask:255.255.255.255

          RX bytes:20198357 (19.2 MiB)  TX bytes:1962241 (1.8 MiB)

then i gave command

# ifdown eth0:1

after which the ip (192.98.102.10) and its interface are gone and there is no ip on eth0 either.

i just made a new test and the crash happened also when i gave wrong ip address to eth0:1.
