[Kamailio-Users] Core dump on xl_get_pai in Openser 1.2.2

[Marcello Lupo]

Hi to all,
i implemented the P-Asserted-Identity and P-Preferred-Identity Header management.
On the development server all is working properly but when i activate the new config on our production system i start to get crashes of the openser process:

openser[31483]: segfault at 0000000000000000 rip 0000000000487853 rsp 00007fff94c9f1a0 error 4
openser[6511]: segfault at 0000000000000025 rip 00000000004214ce rsp 00007fff80f05480 error 4
openser[8967] general protection rip:4214ce rsp:7fff05fbb530 error:0
openser[9872] general protection rip:4214ce rsp:7fffd2b630d0 error:0

I checked the core dump with gdb and i have this info from the core:

Core was generated by `/usr/sbin/openser'.
Program terminated with signal 11, Segmentation fault.
#0  xl_get_pai (msg=0x2b4ad9030d00, res=0x7fffd2b63190, param=<value optimized out>, flags=<value optimized out>) at items.c:1050
1050	    res->rs.len = get_pai(msg)->uri.len;

We are using the 1.2.2 version and i know it is quite old but i like to understand if it happen for some known bug or if i made something wrong.
For the moment is not possible for us to manage the upgrade to a newer version of the proxy till we will not have it redundant on another location.
Thank you for help.
Bye,
MArcello
