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.
