latexdiff 使用简单表格产生错误

Question

我在使用时遇到了一个错误latexdiff，我已将其简化为以下 MWE。给定前后文件...

\documentclass{article}
\begin{document}
\thispagestyle{empty}
\begin{tabular}{ll}
A & B \\
C & D \\
E & F \\
\hline
\end{tabular}
\end{document}

和

\documentclass{article}
\begin{document}
\thispagestyle{empty}
\begin{tabular}{ll}
A & B \\
C & D \\
\hline
\end{tabular}
\end{document}

生成的 diff.tex 文件如下所示。

diff.tex 文件无法编译。控制台输出如下...

? 

我没有足够的经验来理解错误消息，但我知道如果我\hline从两个输入文件中的每一个中删除，那么 diff 就可以很好地编译并产生以下输出。

我的输入文件是否无效？这是一个已知错误吗？是否有任何简单的解决方法可以避免\hline出现错误？
