Do you have to end the crashed session to start a new one? I think we
should keep it open for a while longer (or create a core dump, if that
works?) and still try to test whether it's the
dynlib_close()-might-not-close bug.

Here's what I did to reproduce the crash:
1. create a file "test.el":
;; -*- lexical-binding: t; -*-
(defun testfun (x)
(1+ x))
2. Evaluate:
(require 'comp)
(native-elisp-load (native-compile "test.el"))
(testfun 3)
(fmakunbound 'testfun)
(garbage-collect)
(native-elisp-load (native-compile "test.el"))
Note that this might not always work because of conservative GC.
