My own impression from a while ago is that the address sanitizer was not suitable for the class Emacs undumping, since its shadow memory won't survive dump-restore correctly. It sort of worked in some cases but it didn't work in general. I suppose it may be possible to work around the various issues, but as I recall it'd be a lot of trouble.
