I tried to run bug-hunter on this assertion

(not (string= (format-spec "%s" '((?s . "foo"))) "foo"))

on my init.el and I got

The bug-hunter can't catch invalid-syntax errors. Thas's because it starts operation by reading your entire init file into a list of expressions. So if there's some invalid syntax, the error happens at read-time, before the bug-hunter actually starts doing its thing. (it's technically possible to track-down read-time errors too, but it was never implemented).

@DamienCassou I meet this bug in comment-tags package when using package esup. You can try remove comment-tags. This might helpful. I found this out for a long time.
