(Actually, I was hoping for another case of my bug#60768 wracking havoc, but this issue is actually something different. Even though `beginning-of-defun' is also involved here through `which-function' calls ...) A slightly easier to follow reproducer: - Ensure package "hyperbole" is installed. (Its only role in this issue seems to be a "background load generator", but I'm not 100% sure here.) - Save Hank's Java source P1.java to ~/tmp. - Save the following to ~/tmp/init.el: ------------------------- snip ------------------------- (require 'package) (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/")) (add-to-list 'package-archives '("gnu" . "https://elpa.gnu.org/packages/")) (package-initialize) (hyperbole-mode 1) (which-function-mode 1) ------------------------- snip ------------------------- - Start emacs as ./src/emacs -Q -l ~/tmp/init.el ~/tmp/P1.java and wait for the compiler warnings to calm down. - As Hank has recommended, forward/backward paragraph through P1.java. Rather soon it should hang. And yes, it's which-function-mode which at some level inf-loops. Maybe the timer itself, maybe some upper layer. If I'll find time I could try digging into this.
