The function `xml-parse-region' is never returning from parsing this
specific input. It's saturing a CPU core while using huge quantities of
memory. Fortunately it can be aborted with C-g.
(with-temp-buffer
(insert "<!----><x>< /x>")
(xml-parse-region))
The trigger is a comment followed by at least one opening tag followed
by a stray less-than character. This is not valid XML due to that extra
space in the closing tag, but I'm expecting `xml-parse-region' to signal
an error in the case of invalid input rather than lock up Emacs.
Just for the sake of context, this issue was initially discovered here:
