    My counting may be off, but is that happening after 128 color changes? That close to 2^7 seems suspicious. What OS do you have? What version of xcolor?

    I guess this is a limitation of the xdvipdfmx driver that cannot handle more than 128 groups. Each \color command does a color push.

If I run this code with

xelatex -output-driver="xdvipdfmx -vv" zeno

I get on the console

Each \color command executes

\special {color push \current@color }\aftergroup \reset@color

but the push is never followed by a pop (except at the end of the job).

The color stack apparently has a limitation of 127 or 128 positions (you get red, I get blue, so it can be off by one depending on the version of the software).

Use {\color{<color>}text} or, better,

\textcolor{<color>}{text}

for color changes.

  • Just to provide some relevant info: noted dvipdfm-x's source file pdfcolor.c@r55807 has #define DEV_COLOR_STACK_MAX 128 and if (color_stack.current >= DEV_COLOR_STACK_MAX-1) { WARN("Color stack overflow. Just ignore."); } else { ... }.

  • @muzimuzhiZ Maybe there is more in this than just the definition of a variable.

I encounter this with a beamer with >32 references.

Since each \bibitem will fire 4 color commands, the 31th breaks.

To fix this, I added additional grouping by

\setbeamertemplate{bibliography entry author}{\bgroup}
\setbeamertemplate{bibliography entry note}{\egroup}

If that gives you a missing } before \end{bibliography} error, try

\setbeamertemplate{bibliography entry author}{\bgroup}
\setbeamertemplate{bibliography entry location}{\egroup}

instead.
