1. Start emacs -Q
2. Evaluate the following
(require 'dom)

(with-current-buffer (url-retrieve-synchronously "https://www.seriouseats.com/recipes/2020/06/florentine-omelette-spinach-and-cheese.html")
	(let* ((dom (libxml-parse-html-region (point-min) (point-max)))
	       (scripts (dom-by-tag dom 'script))
	       (json-lds-raw (dom-elements scripts 'type "^application/ld\\+json$"))
               (json-lds (mapcar #'json-parse-string json-lds-raw)))))

Result: segmentation fault.
