[New-bugs-announce] [issue36685] C implementation of xml.etree.ElementTree does not make a copy of attrib argument when creating new Element

[Gordon P. Hemsley]

New submission from Gordon P. Hemsley <gphemsley at gphemsley.org>:

In the process of investigating and writing tests for issue32424, I discovered that the C implementation of xml.etree.ElementTree does not make a copy of the attrib argument when creating a new element, allowing the attributes of the element to be modified outside of creation.

The Python implementation does not have this problem.
