一段时间以来，我亲眼目睹 latexmk 连续 5 次编译我的文档。我以为那是因为我用 beamer 做了非常复杂的事情。
但请考虑以下代码：
\documentclass{article}
\usepackage{fontspec}
\setmonofont{Source Code Pro}
\begin{document}
gh
\end{document}
用 编译它latexmk -pdflua test.tex。它编译一次并生成一个漂亮的 PDF 文件。
现在删除 PDF 文件并运行相同的命令：latexmk 在中止之前编译了 5 次，因为'lualatex' needed too many passes。（注意：在我的正常设置中，我在子目录中进行编译并将生成的 PDF 移回，这就是出现这种情况的原因；如果目标 PDF 仍然存在，latexmk 将根本不会开始编译）。
现在尝试不使用 PDF 和 .aux 文件：编译一次。
尝试不使用 PDF，使用 .aux 但不使用所有其他生成的文件：无休止地编译。
这个恶意的 .aux 文件的内容是什么？这个：
\relax
最后，删除\setmonofont{Source Code Pro}源中的并再次实验：一切正常。事实上，latexmk 说
Changed files, or newly in use since previous run(s):
'/opt/yann/texlive/2018/texmf-var/luatex-cache/generic/fonts/otl/sourcecodepro-boldit.luc'
'/opt/yann/texlive/2018/texmf-var/luatex-cache/generic/fonts/otl/sourcecodepro-regular.luc'
这些文件确实是在编译期间被修改的。
@DG 评论后更新：运行luaotfload-tool --cache=erase允许一次正常编译，但之后问题再次出现。
在所有情况下，日志文件都是相同的：

什么鬼？
lualatex 是版本 1.07.0（TeX Live 2018）。latexmk 是版本 4.61。操作系统是 KUbuntu 18.04。

显然，latexmk 可以被指示通过将以下内容添加到~/.latexmkrc
$hash_calc_ignore_pattern{'luc'}='^';
这只是一种变通方法，而不是真正的解决方案，因为 .luc 文件似乎毫无理由地被 lualatex 触碰。
