Another TeX capacity exceeded, sorry [input stack size=5000]

Question

I got another error as below

TeX capacity exceeded, sorry [input stack size=5000]. [...ial,right= of m0] (A1B1C1) {$A_1B_1C_1$};]

But when i remove the initial in \node [data, initial,right= of m0] (A1B1C1) {$A_1B_1C_1$}; everything is okie. (see the image without the red arrow)

I want that arrow, and I dont know why it got error like that.

PS: In case you wonder about the nested tikzpicture, because I want to create nested node. Acording to this nested node

Answer 1

This is an answer for the red arrow. (I didn't get an error as in David's comments and using pdflatex.)

The trick is setting every initial by arrow at the right place:

% preamble as in the question
\begin{document}
    \begin{tikzpicture}[node distance=1cm,>=stealth',bend angle=25,auto,initial text={}]
        \node [data,initial] (M0) {
            \begin{tikzpicture}
                \node (m0) {\begin{tabular}{c} $M_0$ \\ \_ \\ \_ \end{tabular}};
                \tikzstyle{every initial by arrow}=[red]
                \node [data,initial,right= of m0] (A1B1C1) {$A_1B_1C_1$};
            \end{tikzpicture}
        };        
    \end{tikzpicture}  
\end{document}

or

\begin{document}
        %if need link to inside, use ``remember picture''
    \begin{tikzpicture}[node distance=1cm,>=stealth',bend angle=25,auto,initial text={}]
        \node [data,initial] (M0) {
            \begin{tikzpicture}[every initial by arrow/.style=red]
                \node (m0) {\begin{tabular}{c} $M_0$ \\ \_ \\ \_ \end{tabular}};
                \node [every initial by arrow/.style=red,data,initial,right= of m0] (A1B1C1) {$A_1B_1C_1$};
            \end{tikzpicture}
        };        
    \end{tikzpicture}  
\end{document}
