# Generating a Backtrace

Phalcon is compiled into a C extension loaded on your web server. Because of that, bugs lead to segmentation faults, causing Phalcon to crash some of your web server processes.

For debugging these segmentation faults a stack trace is required. Creating a stack trace requires a special build of PHP and some steps need to be done to generate a trace that allows the Phalcon team to debug this behavior.

Please follow this guide to understand how to generate the backtrace.
