Segmented Fault 11: error (Xcode 15)

I'm encountering an **error Segmentation fault: 11 ** during the archiving process. If the issue is happing with the my code. Then how can I diagnosing the problem. or figure out pin point in code base?

I changed the compiler optimization level. It works for me when I use the Osize compiler optimization level. Previously, it was set to Ospeed.

Want to know about the impact of the Osize compiler optimization level on the app.

Which program is crashing? Xcode itself? Or one of the tools that it sublaunches?
