About the Project Several tutorials exist on how to leverage the GNU Debugger (GDB) to debug misbehaving applications. However, a majority of these blogs just show commands to run that poke at memory addresses, and don’t show the process of resolving said bug. This blog post will walk through how I recently identified, tried to fix, and ultimately reported a bug in dhcpcd via gdb. Identifying The Issue The command line utility coredumpctl is used to interact with the coredumps saved by the systemd-coredump service.
