我有时会遇到致命错误
TeX capacity exceeded, sorry [input stack size=5000].
\reserved@a ->\def \reserved@a
*{\ttl@assign@i {\@tempskipb }}\reserved@a
l.10 \tableofcontents
If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
当我将\renewcommand{\contentsname}{\centering Contents}目录标题放在中间时，我不知道为什么，但对于某些文档，它有效，而对于其他文档，它无效。序言几乎相同。有人知道为什么它有时不起作用，以及我该如何修复它吗？
例如，下面是一份文档，没有工作：
