Python build with frame pointers enabled?

[sk1p]

Comment:

For profiling Python applications, using the Linux perf support in Python 3.12, it would be very helpful to have a build of Python available which has frame pointers enabled. For some additional context: https://www.brendangregg.com/blog/2024-03-17/the-return-of-the-frame-pointers.html

As I'm using conda most of the time to install different Python versions, it would be very nice to have Python w/ frame pointers directly available as a conda package. Is this maybe already available somewhere, or is this something one can realistically build locally? Would that just be a matter of patching recipe/build_base.sh to include -fno-omit-frame-pointer and -mno-omit-leaf-frame-pointer in the CFLAGS and running build-locally.py? Thanks!

I also think it would be worth having a build of CPython (and more generally conda-forge) with frame pointers enabled.

Yes, and yes (this should be sufficient).
