[OpenSIPS-Devel] [opensips] Opensips crash on CANCEL on unanswerd call. (2.1-rc2) (#484)

[vladpaiu]

Hello,

The shm_free checks whether the pointer is inside the SHM memory, and in your case it is entirely out of the memory block, so it looks like a memory corruption. Furthermore, sip_msg_cloner is called with updatable=0 only for replies, but in your case the crash is related to a request.

The source of the crash appears to be a memory corruption - follow the steps at http://www.opensips.org/Documentation/TroubleShooting-OutOfMem in order to enable memory debugging ( see the make menuconfig section ) and reproduce your scenario - OpenSIPS should crash and generate a new core file. Please post the new backtrace after doing this.

Best Regards,
Vlad
