Sorry, something went wrong.
…n concurrent mutations happen (python#127964) We fix a use-after-free in the `find`, `findtext` and `findall` methods of `xml.etree.ElementTree.Element` objects that can be triggered when the tag to find implements an `__eq__` method that mutates the element being queried.

We fix a use-after-free in the find, findtext and findall methods of xml.etree.ElementTree.Element objects that can be triggered when the tag to find implements an __eq__ method that mutates the element being queried.
