The problem, by contrast, sounds more general than that.
Yes, it's a general problem with conservative garbage collection; it's why such garbage collection is called "conservative" rather than "accurate".
If it's essential that GC be accurate, then Emacs shouldn't be using conservative GC. My impression, though, is that the goal is to arrange Emacs's internals so that accurate GC isn't essential. If purify-flag is a counterexample, it's almost surely simpler to change howpurify-flag works than to insist on accurate GC.
What happens if you change this: (setq purify-flag nil) to something like this? (clrhash purify-flag) (setq purify-flag nil)
