It does *NOT* rebind `print-length' and thus inserts incomplete sexps in the temporary file. This then leads to errors during native compilation. `print-level' is also not rebound to nil but it should, too. I don't really understand the failure mechanism, but I am pretty sure that the usage of `prin1-to-string' in `comp-run-async-workers' intends to have a faithful representation of its "expr" local variable in the "temp-file", so that the right thing to do is to rebind those `print-level' and `print-length' variables to isolate `comp-run-async-workers' from whatever the settings the user may have at the time the compilation is started. Redefining `comp-run-async-workers' to bind `print-length' and `print-level' to nil in the big `let*' expression inside the `cl-loop' prevents the reproduction examples below from failing. 1. To reproduce the issue with `print-length' in emacs -Q: (let* ((print-level nil) ;; 16 or lower gives "... error: (void-variable \.\.\.)" ;; 17 gives "... error: (wrong-number-of-arguments setf 17)" ;; 18 gives no error message nor warning (why? No idea!) ;; 19 to 21 (bounds inclusive) give ;; "Error: File is missing Cannot open load file" ;; 22 or higher: no error message nor warning (print-length 16) (temp-file (make-temp-file "reproduce-the-bug" nil ".el")) (_ (with-temp-file temp-file (insert "(defun reproduce-the-bug () nil)\n")))) (native-compile-async temp-file)) ;; *Warnings* buffer pops up with ;; ;; Warning (comp): Debugger entered--Lisp error: (void-variable \.\.\.) ;; ;; or another error message depending on the value of `print-length' 2. To reproduce the issue with `print-level' in emacs -Q: (let* ((print-level 2) ; 3 is already sufficient for the compilation to succeed (print-length nil) (temp-file (make-temp-file "reproduce-the-bug" nil ".el")) (_ (with-temp-file temp-file (insert "(defun reproduce-the-bug () nil\n")))) (native-compile-async temp-file)) ;; *Warnings* buffer pops up with ;; ;; Warning (comp): /AppData/Local/Temp/reproduce-the-bugLyD27F.el: Error: error Cannot find suitable directory for output in `comp-native-load-path'.
