elsarticle 类因作者区块而产生错误

我正在使用 elsarticle 类并尝试使用 TeX Live 2014 编译文档。前置内容部分每次都会产生相同的错误，我不知道如何纠正它。前置内容直接取自 elsarticle 文档中的示例

\begin{frontmatter}
 \title{This is a specimen title\tnoteref{t1,t2}}
 \tnotetext[t1]{This document is a collaborative effort.}
 \tnotetext[t2]{The second title footnote which is  
    longer than the first one and with an intention to fill
    in up more than one line while formatting.} 

 \author[rvt]{C.V.~Radhakrishnan\corref{cor1}\fnref{fn1}}
 \ead{[email protected]}

 \author[rvt,focal]{C.V.~Rajagopal\fnref{fn2}}
 \ead{[email protected]}

 \author[saya]{G.S. Krishna\corref{cor2}\fnref{fn1,fn3}}
 \ead[url]{http://www.sayahna.org}

 \cortext[cor1]{Corresponding author}
 \cortext[cor2]{Principal corresponding author}
 \fntext[fn1]{This is the specimen author footnote.}
 \fntext[fn2]{Another author footnote, but a little more longer.}
 \fntext[fn3]{Yet another author footnote. Indeed, you can have
    any number of author footnotes.}

 \address[rvt]{River Valley Technologies, River Valley Campus,
    Mepukada, Malayinkil, Trivandrum 695571, India}
 \address[focal]{Focal Image (India) Pvt Ltd., River Valley Campus,
    Mepukada, Malayinkil, Trivandrum 695571, India}
 \address[saya]{JWRA 34, Jagathy, Trivandrum 695014, India}
\end{frontmatter}

当我使用 pdflatex 进行编译时，会产生以下错误：

! Argument of \@author has an extra }.
<inserted text>
            \par
l.113 ...f\AB@author{\noexpand\AB@blk@and\@author}

?
Runaway argument?
! Paragraph ended before \@author was complete.
<to be read again>
                   \par
l.113 ...f\AB@author{\noexpand\AB@blk@and\@author}

如果有帮助的话，我可以添加完整的日志文件，但我认为这可能太多了。

答案1

问题是我在序言中加载了 authblk 包，这显然与 elsarticle 对作者块的处理发生冲突。
