Comment (by mojca):

 Oh, every single poppler release breaks texlive in a different way (that
 is: you need a different patch for every single version of poppler), and
 it's not like the trend is about to stop, don't worry about that :)

 And now that poppler requires C++14, upstream TeX Live stopped updating
 poppler (to be able to compile TL on old machines) and as a consequence
 also stopped patching their own sources for pdftex/xetex to be compatible
 with newer versions of poppler. We only hope that someone will step in and
 port pdftex and xetex to pplib, like it was done for LuaTeX. If
 `make_unique` was in fact the only reason for requiring C++14, maybe one
 could actually patch this in TeX Live, but it would be just another time
 bomb until the next poppler version switches to C++17 or random other
 C++14 features anyway.
