I ran "M-x vodil-imenu-expr" when in the file to g= et > the correct imenu entries. But executing "M-x vodil-imenu-bfh" after th= at > I end up with the buffer "Imenu Headings" having only *rescan* in it. When I test your code on one of the built-in Emacs Lisp libraries, e.g. avoid.el, then, on invoking vodil-imenu-expr, I get prompted for an Index item, and typing TAB, the *Completions* buffer pops up containing *Rescan* and nil. I then type C-g and then M-x vodil-imenu-bfh, and the *Imenu Headings* buffer pops up containing just *Rescan*. However, when I start Emacs -Q, evaluate just my emendation of your vodil-imenu-bfh command, then visit avoid.el and invoking vodil-imenu-bfh, the *Imenu Headings* buffer pops up containing this: *Rescan* mouse-avoidance-set-pointer-shape mouse-avoidance-point-position mouse-avoidance-set-mouse-position mouse-avoidance-too-close-p mouse-avoidance-banish-destination mouse-avoidance-banish-mouse mouse-avoidance-delta mouse-avoidance-nudge-mouse mouse-avoidance-random-shape mouse-avoidance-ignore-p mouse-avoidance-banish mouse-avoidance-exile mouse-avoidance-fancy mouse-avoidance-mode So at least the contents of avoid.el does not contain a match for your setting of imenu-generic-expression, and presumably the same goes for the file you tested your code on.
