Re: [SR-Users] Fwd: Stack smash error when using auth_ephemeral with KEMI

Hi Daniel, No, both result in the stack smash error. I've tried with the following deb packages. They all lead to the same issue. - 5.2.1 stable - 5.2.2 stable - 5.2. nightly - devel nightly Core dump for 5.2.1: https://pastebin.com/tTUUk4YH Core dump for 5.2.2 nightly: https://pastebin.com/XHsFAiJp I'm running Kamailio inside a Docker container (using the official Docker image: kamailio/kamailio from Docker Hub). Hope this is clear.
