Here's a reproduction recipe: 0. Build the current native-comp branch, HEAD is af0af63742fd2383dae5627d0ce8167517fd4700 right now. Install the vertico GNU ELPA package and wait for its async native compilation to be finished. 1. emacs -Q 2. Load the ELN file (which is the only one I have, so I'm sure it's the right one for my current emacs): M-x load-file RET ~/.emacs.d/eln-cache/28.0.50-bc702aed/vertico-6eb6690f-90eaf131.eln RET 3. M-x vertico-mode RET 4. Try C-x C-b or C-x C-f to see the problem.
