近期发现的问题，之前并没有出现过，怀疑是什么组件的更新引起的，但是emacs -Q可以复现。
我在wsl下使用emacs，有时会编辑windows下的文件。下面是一个简单的org-mode文件：
* section 1
aaa
* section 2
bbb
* section 3
ccc
放置在Desktop\test\a.org，在wsl下的路径为"/mnt/c/Users/wang1/Desktop/test/a.org"，接着emacs -Q a.org打开文件，然后C-c C-e l p导出为pdf时，minibuffer提示的错误是
org-compile-file: File "/mnt/c/Users/wang1/Desktop/test/a.pdf" wasn’t produced. See "*Org PDF LaTeX Output*" for details
但"Org PDF LaTeX Output"给的信息是

生成的pdf正常，只不过目录下的一些中间文件没有像正常的org-export生成后被清除掉。
不知道咋排查了，求助。
