[I reported this problem on emacs-devel here: https://lists.gnu.org/r/emacs-devel/2019-07/msg00544.html and am sending this to bug-gnu-emacs to get a bug number.]Portable dumping currently can screw up hash tables with user-defined tests. I discovered this over the weekend while looking into Pip Cet's proposed changes to how portable dumping treats hash tables, and have a contrived test case (see attached) that causes gethash to fail with "Lisp nesting exceeds ‘max-lisp-eval-depth’" in an Emacs started via a portable dump, even though the same gethash works fine before dumping.
