[Tex/LaTex] Tex capacity exceeded sorry input stacksize=5000

I am getting this error while trying to build my tex file.
As soon as I include the cleveref package, I get this error and it shows
cleveref.sty with the cursor at the bolded part of the file.

\def\make@df@tag@@@#1{%
    \gdef\df@tag{\tagform@{#1}%
      \toks@\@xp{\p@equation{#1}}%
      \edef\@currentlabel{\the\toks@}%
      \edef\cref@currentlabel{[equation][2147483647][]\the\toks@}}}
**}{}%  end of \@ifpackageloaded{amsmath}**
\@ifpackageloaded{IEEEtrantools}{%
  \PackageInfo{cleveref}{`IEEEtrantools' support loaded}
  \let\cref@orig@@IEEEeqnarray\@@IEEEeqnarray
  \def\@@IEEEeqnarray[#1]#2{%
    \refstepcounter{equation}%

What could be the reason for this error?

svjour3 isn't in texlive but I got a copy from the springer site. It appears to have a bug and your document goes into an infinite loop \cl@chapter is defined to expand to itself. This fixes (or at least avoids) that immediate problem.

\begin{filecontents*}{example.eps}
gsave newpath 20 20 moveto 20 220 lineto 220 220 lineto 220 20 lineto closepath 2 setlinewidth gsave .4 setgray fill grestore stroke grestore \end{filecontents*}
\RequirePackage{fix-cm} 
\documentclass[smallextended]{svjour3} 
\smartqed \let\proof\relax \let\endproof\relax

%\def\cl@chapter{\cl@chapter \@elt {theorem}}%bug in class
