Import this script from osmo-ci dfa9fcca ("scripts/wrapper_core_bt_on_error: new script"), so it can be used in ttcn3-asterisk-ims-ue-test in a follow-up patch.
ttcn3-asterisk-ims-ue-test: show trace on coredump
Use wrapper_core_bt_on_error.sh to show a backtrace in case asterisk crashes and a coredump is generated. Set CWD to /data, so the core and core.backtrace files end up in the jenkins artifacts.
The result looks like this (forced a segfault in main() to test this): $ cat asterisk-ipv4/core.backtrace [New LWP 18] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
