Access to the internals is protected by validity checks that signal
Lisp-level errors instead of letting Emacs crash. Emacs crashing is a
bad problem because you lose your editing session, so Emacs strives to
avoid crashing.
About the only thing I know of that a Lisp program can do to crash
Emacs is to trigger infinite recursion, and even that has protection
in Emacs, albeit not 100% reliable.
