Not sure I understand: you get no Index at all, or do you get an empty Index?
I get an index page with (Index is nonexistent) instead of an index.
Then I cannot reproduce this with a recent master. I guess it's
something related to your installation of TeX or Texinfo. Does
elisp.log say something about the index?
