Corrupted PDF with lualatex + gs 10.04.0

[Denis Bitouzé]

Hi,

I sent the following message to the dev-luatex mailing list. I was
informed that it was on hold until the list moderator could review it
for approval. As nothing has happened for several days, I have posted it
here in the hope that someone here who is a member of this mailing list
can post it for me.

  │ Hi,
  │ 
  │ I recently encountered an issue with LuaTeX (1.18.0) + Ghostscript
  │ (10.04.0) and it turns out that the culprit seems to be LuaTeX :) This
  │ may be summarized as follows:
  │ 
  │ 1. Compile with `lualatex` the following `test.tex` file:
  │ 
  │ \documentclass{article}
  │ \begin{document}
  │ Foo.
  │ \end{document}   
  │ 
  │ 
  │ 2. Run then the following command:
  │ 
  │ gs -V -P- -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr "-sOutputFile=test.pdf.pdf" test.pdf
  │ 
  │ On GNU/Linux, this returns:
