自 v1.6 以来，我一直在成功地使用 Doxygen 为一个相当大的 Fortran 90 项目生成 PDF 文档。在最近升级到 Doxygen 1.8 后，pdflatex 因我无法理解的错误而窒息。来自 refman.log：

查看 classm__aerosol.tex 的前 25 行，没有明显与错误消息匹配的内容：
\hypertarget{classm__aerosol}{\section{m\-\_\-aerosol Module Reference}

没有什么明显与最近读取的块“\LT@LL@FM@cr”相匹配，而且我不知道足够的低级 TeX 将其翻译成可能实际上在源文本中的内容。
怀疑这可能已在比 Linux Mint (v1.8.1.2) 附带的更高版本的 Doxygen 中得到修复，我从源代码构建并安装了 v1.8.3.1，更新了我的 doxyfile，清除了旧文档并重新生成它。我得到同样令人困惑的错误。
refman.log 中没有任何明显的迹象表明 LaTeX 包丢失或损坏，我完全不知道是什么原因造成的。
