Stack size limit error with hyperref

I'm trying to typeset a 75 page document using the hyperref package,
and I'm getting this error message: ! TeX capacity exceeded, sorry [input stack size=5000]. Is the hyperref package a stack hog? Is this normal on a less-than-book-size 75 page document? How can the stack size be increased? The log file says: If you really absolutely need more capacity, you can ask a wizard to enlarge me.

I've seen this before with hyperref, particularly with special characters (such as '~') used incorrectly within a URL. I'd guess that you have defined a macro that expands to something containing a '~' (or perhaps '#' or '&'), then tried to use this as the URL part of an \href or similar command. That cannot work.

Ross,
Thanks, you got me on the right track! It turns out that hyperref does not like to see a \bm command inside of a section name. It also crashes with a \boldsymbol, but not with a \mathbf, although the \mathbf doesn't seem to do anything within a section name. I'm using the article class, and section names are typeset in bold. When there is a $...$ string embedded in the section name, it is not set in bold and it doesn't look good. The \bm command used within the $...$ string, for example $\bm{\beta T}$, corrects this. \tableofcontents does not seem to have a problem with this, but hyperref crashes. So how do I get the $...$ string to be typeset in bold within the section name, consistent with the rest of the name, and not crash hyperref?

Hi Richard The problem here is that section commands, by rights, should not contain formatting commands because they well may be used in other parts of the document (running headers and the table of contents, specifically). Any formatting you desire should be declared by redefining the article class's \section command or by using one of the various packages to do so. In this case, I've just copy/pasted the definition from article.cls, changed \newcommand to \renewcommand, and added \boldmath to the end of the font command. \boldmath is to maths what \bfseries is to text, in case you haven't seen it before. Unfortunately the Table of Contents makes a similar oversight and we need to patch that up as well in exactly the same way. Best of luck, Will Robertson \documentclass{article} \makeatletter \renewcommand\section{\@startsection {section}{1}{\z@}% {-3.5ex \@plus -1ex \@minus -.2ex}% {2.3ex \@plus.2ex}% {\normalfont\Large\bfseries\boldmath}} \renewcommand*\l@section[2]{% \ifnum \c@tocdepth >\z@ \addpenalty\@secpenalty \addvspace{1.0em \@plus\p@}% \setlength\@tempdima{1.5em}% \begingroup \parindent \z@ \rightskip \@pnumwidth \parfillskip -\@pnumwidth \leavevmode \bfseries\boldmath \advance\leftskip\@tempdima \hskip -\leftskip #1\nobreak\hfil \nobreak\hb@xt@\@pnumwidth{\hss #2}\par \endgroup \fi} \makeatother \usepackage{amsmath,bm,hyperref} \begin{document} \tableofcontents \section{No problem: $\int^{2\pi}_0\cos\theta\,\mathrm{d}\theta=0$} Now in running text: $\int^{2\pi}_0\cos\theta\,\mathrm{d}\theta=0$. \end{document} --------------------- Info --------------------- Mac-TeX Website: http://www.esm.psu.edu/mac-tex/ & FAQ: http://latex.yauh.de/faq/ TeX FAQ: http://www.tex.ac.uk/faq List Post: <mailto:[hidden email]> |

While I agree with the sentiments expressed by Will concerning formatting commands within section-titles, there is in fact a way to avoid the difficulties that you are encountering, without editing .sty files. First of all, let's try to understand what is going on. To make a bookmark from your section's title, hyperref needs to construct a string that will be displayed in the 'Bookmarks' window of the PDF browser. This requires expanding all macros that occur in the section-title. However, it is just trying to get the correct text to display, and does not care about styles or spacing. Those aspects are all pre-determined, and only standard characters are allowed. Thus the \bm is quite irrelevant, yet still needs to be expanded, as it might (but doesn't) contain characters. The infinite loop occurs because some things in the expansion of \bm occur within a quite different context from what it was designed to handle. So the best thing to do is to give \bm a temporary expansion of nothing (i.e., the empty string), at the critical time when the expansion occurs for constructing the bookmark's anchor-text. There is a standard mechanism in hyperref.sty to do just this: \pdfstringdefDisableCommands{\def\bm{}\def\beta{ beta }} Note that pdfTeX doesn't yet know how to put a real \beta into the bookmark, so rather than get nothing, we put 'beta' spelt out instead, and with some space around it. As I've not had a chance to test your actual source coding, this is just my best guess at what I think is going wrong for you, and how to fix it --- based upon past experience of similar problems, of course. So if the above doesn't help, please send an explicit example, cut down as much as possible. > > Richard S?guin > > On Mar 24, 2005, at 1:13 AM, Ross Moore wrote: > >> Hi Richard, >> >> >> On 24/03/2005, at 3:33 PM, Richard Seguin wrote: >> >>> I'm trying to typeset a 75 page document using the hyperref package, >>> and I'm getting this error message: >>> >>> !
