I'm writing a paper using a cls file provided by the journal (which I cannot modify). They are using some tricky code for creating table notes under tables. Problem is that this code crashes under my MacPorts version of TeX Live (while working fine on a colleague's linux machine) with the following message:

! TeX capacity exceeded, sorry [input stack size=5000].
\font@name ->

I've tried modifying texmf.cnf by increasing stack size, that doesn't fix the problem.

I'm not quite good in understanding the original code, but after some reverse engineering I was able to compose a MWE:




    \thecounter #2


My\ref{l1} print\ref{l2}:

If I replace




everything works fine and I even get the correct result: Result

Another thing that fixes the problem is replacing




(or with \roman or \Roman)

Here's the full output of pdflatex -version:

Is this a bug or is something missing from my TeX Live installation?

  • Ideally we'd have the versions for the files you are using (add \listfiles to you input), rather than the rather vague TeX system description. Luckily, here I can see the issue .... – Joseph Wright Nov 13 '15 at 18:52
  • @JosephWright just in case I updated the OP with the \listfiles output – SiLiKhon Nov 13 '15 at 19:11

The LaTeX team recently (start of 2015) integrated the fixltx2e package into the kernel. There are a small number of places where this may cause issues, primarily where people have relied on problematic behaviour. Here, the class is relying on the expansion safety of \thecounter (or rather of the code to make footnote symbols), which it should not do. The code should be

    \protected@xdef\@currentlabel{\thecounter}% Change here
    \thecounter #2

Of course, for a fixed class you can't alter that. What you can do is back out the kernel changes by adding


right at the start of you document (before \documentclass). This will undo all changes to LaTeX since the end of 2014 and so will allow you to compile.

  • Thanks for the answer. The "protected" thing does work indeed, while "RequirePackage" doesn't seem to have any effect... – SiLiKhon Nov 13 '15 at 19:05
  • @SiLiKhon It really should: with your example adding that line works fine for me (I have a very up-to-date TeX system). – Joseph Wright Nov 13 '15 at 19:10
  • Can it be Mac Port issue at this point? :) I've tried feeding in different dates, tried placing this line in different places, nothing changes. Although I do get some warnings when requesting 0000/00/00... – SiLiKhon Nov 13 '15 at 19:33

    @SiLiKhon It could be a file version issue: if you add latexrelease to your document, what does it show for the date/version in \listfiles? – Joseph Wright Nov 13 '15 at 19:50
  • For latexrelease.sty it has "latexrelease.sty 2015/05/09 v1.0d LaTeX release emulation and tests", all the other files are same as in the OP – SiLiKhon Nov 14 '15 at 0:10
