What you should do is giving a small example of this in plain TeX, as a 
lot of people on the list don't use LaTeX at all. The best thing would 
be to extract some code from LaTeX to see what's going on when you type 
\begin{equation}xx\end{equation} in LaTeX, and to see where the bug is 
in this code. With this the LuaTeX team will be able to work on the bug.

Thank you,
