If you build without debug info in the first place, it does work, at
around the same size. Also if you strip temacs before dumping, it
works. The problem is only in stripping a dumped binary that had
debug info to start with. It seems the strip command removes some info
that Emacs needs to reconstruct the heap from the dumped image.
