In this MWE, of a math equation

\documentclass{article}
\begin{document}
\begin{equation}
\sqrt{\frac{\left(E-\frac{N_c e^d}{b}\right)}{a}}
\end{equation}
\end{document}

I find that lualatex (Version beta-0.70.2-2013031016 (TeX Live 2013/dev)) produces a very strange result:

lualatex

The result is however as expected with pdflatex 3.1415926-2.5-1.40.13 (TeX Live 2013/dev) and xelatex (3.1415926-2.5-0.9999-2013031016 (TeX Live 2013/dev))

The example is really minimal to reproduce the bug.

The question is: I really need to type an equation like this and I really need to use lualatex for other reasons. What is a workaround (trick with commands) or a permanent solution (e.g. load package, add something to the preamble)?

A secondary question is how one reports a bug in lualatex?, (or for any TeX program for that matter)

use 

\usepackage{unicode-math}

It should be fixed in the current version 0.75. See also: How to report a bug in LuaTeX?
