Hi all,
I encounter a BUG with org-toggle-latex-fragment on an equation that
uses amsmath's split environment.
(Exporting of the document works fine.)
The problem is that the \begin{equation},\end{equation} get stripped of
the temporary tex file.
Here is some test doc
--8<---------------cut here---------------start------------->8---
#+TITLE: Test amsmath's split
* Some equation
with some split expression, e.g.
\begin{equation}
\begin{split}
w \cdot x + b &= 1, \text{ and}\\
w \cdot x + b &= -1
\end{split}
\end{equation}
To reproduce try to org-toggle-latex-fragment (C-c C-x C-l) on that
latex expression.
Export of this works fine.
--8<---------------cut here---------------end--------------->8---
which results in this /tmp/foobar.tex document (relevant parts shown):
--8<---------------cut here---------------start------------->8---
\begin{document}
\definecolor{fg}{rgb}{0.996109,0.996109,0.996109}
\definecolor{bg}{rgb}{0.197269,0.197269,0.197269}
\pagecolor{bg}
{\color{fg}
\begin{split}
w \cdot x + b &= 1, \text{ and}\\
w \cdot x + b &= -1
\end{split}
}
\end{document}
--8<---------------cut here---------------end--------------->8---
The compilation of that results in

| ERROR: Package amsmath Error: \begin{split} won't work here.
