Forgive me if you know all this already: 1. Compile with debugging enabled (use the -g flag to gcc) 2. Use ulimit to enable core dumps: ulimit -c unlimited 3. Run your program in the same shell as where you ran ulimit and allow it to seg fault (it should the create a file called "core" or "core.<pid>" where pid is the process ID (a number). 4. Use gdb to obtain a stack trace: "gdb <your program> <core file>". At the prompt, type "bt" Things may be a little more complicated since you're writing a plug-in, but the above should get you going.
