Run lualatex with the document below, and observe that it fails. It's most likely because some package versions don't really get along well. See this for details: http://tex.stackexchange.com/questions/68500/unicode-math-with-amsmath-new-error \documentclass{article} \usepackage{amsmath} \usepackage{unicode-math} \begin{document} $Test(v)$ \end{document} Reproducible: Always
I should mention that it's a problem with the latest texlive 2012 in tree.
