Since Perl 5.26.0, braces in RegExps have to be escaped if one wants Perl to match these literally.
However, texlive@2017 --- from June 4th, 2017 --- doesn't implement the fix made to latexdiff ([1][2]) --- made into TeX Live repository in June 26th, 2017. Without the fix, `latexdiff' command is unable to work (its goal is to generate "TeX-command-and-group-aware" differences between LaTeX documents).
