Adjust profiling call stack depth

[lastquestion]

Apparently the default is 16, that's way too low. I was looking at profiles and the depth often already was 10-12 for relatively simple commands.

• Double check my guess why that is in the native code in profiler.c

Hat tip to reddit user /u/cpitclaudel for pointing this out.

You might want to ask emacs-devel about this or report an Emacs bug, I've received useful advice from Stefan Monnier on the topic for https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22114.

Thanks for sending it to me, very interesting. I totally have been on both sides of the personalities of that devlist, so I'm quite empathetic to all parties involved.

But I really appreciate that you fixed the bug I worked around at https://github.com/lastquestion/explain-pause-mode/blob/master/explain-pause-mode.el#L364-L372

The patch will land sometime in 27.x, then, right? I'll probably do a version check and polyfill backwards to 26 keeping the same workaround, which technically reaches into a private method of packages, but in elisp land everything's exposed anyway so ... 😀

Yes, going by Git it should safely land in Emacs 27.1

This just happened in the wild. #14 shows a callstack that broke in half because the depth was too high.
