To: 53532
Package: Emacs
Version: 29.0.50
% make (with native compiler)
[...]
% touch lisp/emacs-lisp/{cl-macs,byte-opt,comp}.el
% make -j4
[...]
Warning: Eager macro-expansion skipped due to cycle:
… => (load "byte-opt.el") => (macroexpand-all (defalias 'byte-decompile-bytecode-1 …)) => (macroexpand (cl-symbol-macrolet …)) => (load "comp.el") => (macroexpand (eval-when-compile …)) => (load "byte-opt.el")
[...]
I haven't yet managed to turn this eager-macroexpansion cycle warning
into an actual error, but it'd be good to get rid of this
cyclic dependency.
I'm not sure how we go from (macroexpand (cl-symbol-macrolet …)) to
loading `comp.el` but I suspect that's where the problem lies.
