# Issues with star environments inside paracol package

This question led to a new vesion 1.32 of paracol package.

Basically I want to use the paracol package to set bilingual texts including figures & tables, some of them should span two columns.

Figures & tables spanning one column work perfect, but with figure* and table* environments spanning two columns, the right column get corrupted. The space needed isn't considered in the right column, resulting in overlapping text with figures*|tables*

MWE, which is based on "tcolorbox Spanning Two Columns in {paracol} Environment" and paracol-man:

\documentclass[10pt,twoside,a4]{article}

\usepackage[latin,english]{babel} % proper  multilingual hyphenation
\usepackage{lipsum}
\usepackage{graphicx} % include images
\usepackage{paracol} % multilingual documents

\begin{document}\sloppypar

\begin{paracol}{2}

\lipsum[1]
\lipsum[2]
\begin{figure*}
\def\arraystretch{0.8}
\centerline{\begin{tabular}[b]{|c|}\hline
\hbox to.9\textwidth{}\\ \\ \\
double-column figure \#1\\ \\ \\
\\\hline
\end{tabular}}
\caption{A Double-Column Figure}
\end{figure*}
\lipsum[3]
\lipsum[4]

\switchcolumn

\lipsum[5]
\lipsum[6]
\lipsum[7]
\lipsum[8]

\end{paracol}
\end{document}


Resulting in (top of pg 2):

BTW: same effect, if I'm running the MWE of "tcolorbox Spanning ..."

Summary: I try to understand my issue by using examples I found here, on my computer, always resulting in the same difference: in the right column, the space which should be used for star environments isn't allocated. (using LateX since 1997).

I'm using a fresh install of MiKTeX 2.9

• This is the expected behaviour. If you want something different, then you have to work around it. Here you can break the paracol environment to set the two-column figure, or you can line up the two columns and leave the gap manually. Either would work, but it's not clear from your example how you intend to provide bilingual content if they don't match up. Oct 8 '15 at 21:19
• @Werner I think this is a bug. It works fine with TeX Live 2014 but not 2015. Should it be reported to the package maintainer, do you think? Or am I missing something? (I don't know this package at all - I just compared the 2014 and 2015 output for a test case.)

• @OP What do you mean that this happens with any LaTeX from 1997 or later?

• internal latex commands \end@dblfloat and \@dblfloatplacement are changed since v1.2b 2015/01/11 make paracol no more compatible with new format (in this point). Oct 9 '15 at 9:23
• @touhami: That's worth to be the answer, in my point of view!
