Sorry, this got lost in my inbox. assert(false) sends SIGABRT to the process. The default behavior is to dump a core file that can be analyzed later with GDB. Your system must have core dumps enabled (i.e. ulimit -c unlimited). Also, various pieces of software like systemd's coredumpctl can influence where and how core dumps are stored. But in short, an assertion failure produces a core dump. Stefan
