Unfortunately, it doesn't seem to reproduce on my side.  I tested with
emacs 25.2 on windows 10 and AUCTeX 12.1.1 from elpa.  The file you
provided just compiles smooth with the file name "aa.tex".

Running `LaTeX' on `aa' with ``pdflatex  -file-line-error   
-interaction=nonstopmode "\input" "aa.tex"''
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/W32TeX) 
(preloaded format=pdflatex)
 restricted \write18 enabled.

Does anyone else experience the same problem with Liyu?

I have no idea currently why such version dependency exists, since the
newest version 12.1.1 works without problem on my side.

Additional information might be helpful, e.g.
- The output of M-x TeX-submit-bug-report
- The content of the process buffer (displayed by C-c C-l)
- The path name of directory where aa.tex is saved
- The type and year of your TeX distribution
- Whatever you think might be clue to resolve this issue
