Frame pointers are extremely useful for quickly generating accurate stack traces when debugging and profiling release builds. In particular, it allows the use of Linux's perf stack, which offers high-performance profiling but only supports unwinding via frame pointers, barring some extremely slow workarounds: https://blogs.gnome.org/chergert/2022/12/31/frame-pointers-and-other-practical-near-term-solutions/

Nice! I just tested this patch with a program I was analyzing with linux perf tools, and most of the unknown symbols are now explained 🥳 Weirdly I returned to crystal 1.10.1 without the frame pointers, and perf still finds the symbols 🤨 |
