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:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
Foo.
\end{document}
--8<---------------cut here---------------end--------------->8---
2. Run then the following command:
--8<---------------cut here---------------start------------->8---
gs -V -P- -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr
"-sOutputFile=test.pdf.pdf" test.pdf
--8<---------------cut here---------------end--------------->8---
On GNU/Linux, this returns:

You can find more details on how I came to LuaTeX in the TeX Live
mailing list archive and on the Ghostcript's Bugzilla:
