我有一些 xelatex 代码，它们曾经可以在以前的系统上运行，但在新安装（KDE Neon（Ubuntu 20.04）、tex-live 2021、ghostscript 9.54）上不再运行。
我使用 memoir 设置 5 毫米的裁切标记。字块为 140 x 140 毫米，但当我创建pspicture140 x 140 毫米的字块时，它似乎实际上创建了 150 x 150 毫米的画布，因此与整个库存尺寸相对应。在下面的例子中，数字 1、2、...、9 应该放置在字块的边缘和中心，但它们之间的距离太远（对应于裁切标记的额外宽度）。

答案1
我想我已经能够弄清楚这件事是怎么出错的了。
\pagewidth实际上是 luatex 宏（不确定从什么时候开始）。2018 年（v3.7g），在 memoir 的\mem@fixpagelayout宏（在 处执行\begin{document}）中添加了一个检查，该检查设置\pagewidth为等于\stockwidth，但前提\pagewidth是 已经定义。
因此，这不是用户宏意外覆盖包宏的情况（因此没有警告），而是反之亦然！
