[Philipp Gesang]

Hi Michael,

thanks for testing!

Fractions and text figures (onum) appear to be mutually
exclusive. Test for plain:

  \input luaotfload.sty
  %\font\libertineregular="name:Linux Libertine O:+frac;+onum" \libertineregular
  \font\libertineregular="name:Linux Libertine O:+frac" \libertineregular
  foo 1/2 \quad 1/5 \quad 355/530 \quad bar
  \bye

And latex/fontspec:

  \documentclass{article}
  \usepackage{fontspec}\setmainfont{Linux Libertine O}
  \begin{document}
    {\addfontfeature{Fractions=On}
     +onum: 1/2 \quad 1/5 \quad 355/530 \quad}\endgraf
    {\addfontfeature{Fractions=On,Numbers=Lowercase}
     +frac;+onum: 1/2 \quad 1/5 \quad 355/530 \quad}\endgraf
  \end{document}

Not really. But judging from your logs your luatex binary is
*really* out of date. There’s even warning:

    Module luaotfload warning: LuaTeX v0.70 is old, v0.76 is recommended.

The font loader relies on Luatex features like node.end_of_math()
so it is likely to break with your binary. Are you certain that
you did a complete update?

Best
Philipp
