I am using \pgfkeys to help organize custom symbols. However, I ran into a problem when trying to execute a key inside \section command.

\documentclass{article}
\usepackage{tikz}
\pgfkeys{a-key/.code={a-value}}
\begin{document}
    Test \pgfkeys{a-key}
    \section{\pgfkeys{a-key} section} % <- doesn't work
\end{document}

In this example, my pdflatex just freeze while compiling without giving error message. Have I done something wrong? Is executing a \pgfkeys possible in \section?

\protecting gets things back on track.

\documentclass{article}
\usepackage{tikz}
\pgfkeys{a-key/.code={a-value}}
\begin{document}
    Test \pgfkeys{a-key}
    \section{\protect\pgfkeys{a-key} section} % <-  works
\end{document}
