Hi
version: kamailio 5.7.6 (x86_64/linux) on Ubuntu from the: http://deb.kamailio.org/kamailio57 repository
AOR alice has 4 contacts with q=0.5 AOR bob has 1 contact with q=0.5
I can reproduce a crash with this code snipplet:
xavp_rm("contact_stack"); # Make sure XAVP does not exist. lookup("location", "sip:alice@example.com"); t_load_contacts(0); # after this, $xavp(tm_contacts) has four elements $xavp(contact_stack) = $xavp(tm_contacts); # Store the four elements on my stack # Verify, $xavp(contact_stack) now has four elements, copy successfull. lookup("location", "sip:bob@example.com"); # after this, $xavp(tm_contacts) has one element $xavp(tm_contacts) = $xavp(contact_stack); # Append the four previously saved contact with the one in $xavp(tm_contacts)
if (!t_next_contacts()) { xlog("L_INFO", "$cfg(route): ERROR NO CONTACTS LOADED \n"); sl_send_reply("500", "Server Internal Error - Cannot get contacts"); } # Load contacts into destination set to parallel fork to five contacts.
=> segmentation fault!
Shall I open an issue on github or am I performing a forbidden action?
I'm doing some more test to find out where exactly the crash occurs. I'm not sure if it happens when adding to tm_contacts of when calling t_next_contacts.

Hello Benoit,
even if it would be a "forbidden action", Kamailio should not crash. Please open an issue for this problem.
Thanks,
Henning
