Description
Description
After updating Texlive on September/2025 the "figure" environment prevented compilation with tex capacity exceeded error. However, if only "figure*" is used, then compilation is normal.
Minimal Working Example
\documentclass{kaohandt}
\usepackage{subcaption}
\begin{document}
\begin{figure}
\centering
\begin{subfigure}{\textwidth}
Figure I
\caption{Test FigA1.}
\label{fig:A1}
\end{subfigure}
\begin{subfigure}{\textwidth}
Figure II
\caption{test figA2}
\label{fig:A2}
\end{subfigure}
\caption{Test figure.}
\label{fig:All}
\end{figure}
Test Fig.~\ref{fig:All}.
Test sub-labels \ref{fig:A1} and \ref{fig:A2}.
\end{document}Expected behavior:
A figure inserted outside margin.
Actual behavior:
There is an error:
document.tex: error: 20: TeX capacity exceeded, sorry [parameter stack size=20000]. \caption{Test figure.}
Additional Information
If the caption line "\caption{Test figure.}" is commented out the compilation proceeds but without the figure caption.
If "figure*" is used instead of "figure" the compilation and cross-references are all ok.
