Hi Tassilo and all,

I can reproduce on TeX Live what Hugo and Tobias say.

I replaced "use_any_eps_file_here" with "tiger" and saved the file under
the name "xyz.tex". And I created symbolic link of tiger.eps in the
current directory (in my case, /tmp/):
ln -s /usr/local/texlive/2021/texmf-dist/doc/generic/pstricks/images/tiger.eps .

And I issued pdflatex in my shell (not using AUCTeX):
pdflatex -shell-escape xyz.tex

Then I got ghostscript error during the automatic invocation of ps2pdf:
=== pstool: ps2pdf ===
Error: /typecheck in --div--

See the attached test kit (not including the symlink of eps file).

It seems that the usage of "example-image" is the source of trouble. In
that case, I find in the log that "example-image.tex" is read in, not
"example-image.eps".

That's because "example-image.tex" contains tikzpicture environment. So
I infer that "example-image" isn't suitable to specify as an argument to
\psfragfig.

I experienced similar error with Hugo's example as well if I used the
command pdflatex, not latex when typesetting.
