Bug#752773: Bug report: the new listings.sty yields failures

[Norbert Preining <preining@logic.at>]

Dear Jobst,

one more thing: On the TeX Live mailing list Qing Lee send a fix:

**********************8
It seems that listings used brace trick in a wrong way since 2014/03/04 v1.5c:
...
    % \lstthanks{Luc~Van~Eycken}{Luc.VanEycken@esat.kuleuven.be}{2014/01/22}
    % reported, that the experimental implementation of |\lstinline| with
    % braces instead of characters surrounding the source code resulted in an
    % error if used in a tabular environment. He found that this error comes
    % from the master counter (cf. appendix D (Dirty Tricks), item 5. (Brace
    % hacks), of the TeXbook (p. 385-386)). Adding the following line remedies
    % the wrong behaviour.

A quick fix is

    \makeatletter
    \renewcommand\lstinline[1][]{%
        \leavevmode\bgroup % \hbox\bgroup --> \bgroup
          \def\lst@boxpos{b}%
          \lsthk@PreSet\lstset{flexiblecolumns,#1}%
          \lsthk@TextStyle
          \ifnum\iffalse{\fi`}=\z@\fi
          \@ifnextchar\bgroup{%
            \ifnum`{=\z@}\fi%
            \afterassignment\lst@InlineG \let\@let@token}{%
            \ifnum`{=\z@}\fi\lstinline@}}
    \makeatother

Hope that helps
