Memory error with tabular and latest Tex4ebook running on Texlive 2018

Question

This is a followup of my question here and uses the same MWE and the config file provided by michal.h21.

MWE

\documentclass[ebook,12pt,oneside,openany]{memoir}

\usepackage{lipsum}

\setsecheadstyle{\normalsize\itshape\raggedright}%

\title{Book}
\author{Author}
\date{}

\begin{document}

\maketitle

\frontmatter

\tableofcontents \newpage

\mainmatter

\chapter{C1}

\section{S1}

\begin{tabular}{p{0.3\hsize}p{0.7\hsize}}%
a & b\\
\end{tabular}

\end{document}

Config file:

\Preamble{xhtml}
\Css{h3.sectionHead{font-style:italic;font-weight:normal;}}
\begin{document}

\EndPreamble

This gives an error message running Tex4book:

! TeX capacity exceeded, sorry [input stack size=5000].
\n:@startpbox: ...\expandafter \o:@startpbox: \fi
                                                  {#1}\expandafter \everypar...
l.26     a
           & b\\
If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

It worked previously without any problems.

Is there a way to fix this? Thanks.

Answer 1

It seems that some packages have been recently removed from Memoir:

Changed (2018/12/12)

o memoir v3.7h

-- The following packages are no longer embedded into the class sources: array, delarray, dcolumn and tabularx.

tex4ht config file for Memoir includes configurations for these packages and it seems there is a clash somewhere. Fortunately, disabling loading of these files from memoir.4ht seems to fix the error:
