When I compile the following mwe with xelatex, I am told:
ERROR: LaTeX Error: Command \dddot already defined.
--- TeX said ---
Or name \end... illegal, see p.192 of the manual.
l.571 \hbox{\normalfont ...}\vss}}}}
(That's line 571 of amsmath.sty).
\documentclass{minimal}
\usepackage{fontspec}
\setmainfont{LinLibertine_R.otf}
\usepackage{unicode-math}
\setmathfont{STIXGeneral}
\usepackage{amsmath}
\begin{document}
Hello, world.
\end{document}
Is there a bug, or am I doing something wrong?
That allows compilation, but the braces are minuscule (the first one is supposed to span Ordinarium/Extraordinarium). Here's the longer example.
\documentclass{minimal}
\usepackage{mathtools}
\usepackage{unicode-math}
\setmainfont {LinLibertine_R.otf}
\setmathfont{STIXGeneral}
\begin{document}
\[
\begin{tabular}{c}
Somnium\\
proprie\\
dictum
\end{tabular}
\left\{\begin{array}{@{}l@{}}
\text{Ordinarium}
\left\{\begin{array}{@{}l@{}}
\begin{tabular}{@{}l@{}}
Vulgare seu commune\\

\end{tabular}
\left\{\begin{tabular}{@{}l@{}}

\end{tabular}\right.\\[6\jot]
\text{Proprium aliquibus.}\\

\end{array}\right.\\[12\jot]

\left\{\begin{array}{@{}l@{}}
