Hi
We have compiled & installed the sofia sip library on the
scratchbox. We have been tryig to get sofsip-client running.
Everytime after the client registration, a segmentation fault
occurs.
We are attaching relevant logs. The crash occurs in stun_dns.c:91.
The error reads as follows:
hn-wm.c:302,hn_wm_top_service() ### Failed to read memory limits,
using scratchbox ??
hn-wm.c:335,hn_wm_top_service() unable to find service name 'xterm'
in running wins
hn-wm.c:336,hn_wm_top_service() Thus launcing via osso_manager_launch()
hn-wm.c:1210,hn_wm_dbus_method_call_handler() Checking if service:
'com.nokia.xterm' is watchable
hn-wm.c:1225,hn_wm_dbus_method_call_handler() Showing Launchbanner...
Program received signal SIGSEGV, Segmentation fault.
0xb7f7144e in priv_sres_cb (self=0x8081488, q=0x8082a80, answer=0x0)
at stun_dns.c:91
91 for (i = 0; answer[i] != NULL; i++) {
Do we have a patch to solve this problem?
Thanks
