bug#48383: [native-compile] Debugging external package powerline.el

[Arash Esbati]

Hi all,

I have successfully built Emacs with native-compile support on Win10[1]
and it works fine -- many thanks for this.

I've also installed powerline package from MELPA and Emacs fails to
compile the package with this error:

    x:/pathto/.emacs.d/elpa/powerline-20210428.1229/powerline.el:
    Error: List contains a loop ("22", . #0)
    Compilation finished.

How can I get more info about the error from the compiler?  Currently
Emacs tries to compile the package each time it starts (and fails) and
that makes the start slower.

TIA for any hint.

Best, Arash
