It seems that listings used brace trick in a wrong way since 2014/03/04 v1.5c:

     \newcommand\lstinline[1][]{%
         \leavevmode\bgroup % \hbox\bgroup --> \bgroup
           \def\lst at boxpos{b}%
           \lsthk at PreSet\lstset{flexiblecolumns,#1}%
           \lsthk at TextStyle
           \@ifnextchar\bgroup{%
     %    \end{macrocode}
     % \lstthanks{Luc~Van~Eycken}{Luc.VanEycken at 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.
     %    \begin{macrocode}
             \ifnum`{=0}\fi%
             \afterassignment\lst at InlineG \let\@let at token}%
                              \lstinline@}

A quick fix is

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