pdfTeX autoexpansion error when abstract field extends beyond 87 characters

[katarapkokid]

OS: Ubuntu 20.02. pdfTex: This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) (preloaded format=pdflatex 2023.6.1)

Simple modification of someone else's package (gde23.synctex.gz attached below) causes pdfLaTex to generate the following errror:

[1
! pdfTeX error (font expansion): auto expansion is only possible with scalable 
fonts.
\@EveryShipout@Output ...@Org@Shipout \box \@cclv 

l.69 \end{document}

!  ==> Fatal error occurred, no output PDF file produced!

This is reproducable by using gde23.synctex.gz. The file gde23.tex has been edited to extend the number of characters in the abstract. Once the number of characters in the abstract reaches 87, the error appears.

Removing the final zero 0 in the abstract text, and the error disappears, and pdf is produced.

Sorry, but I cannot reproduce this error. I used Overleaf for different TeXlive versions.

Hi Dimitry,

Thanks for trying. I, too, have it working in Overleaf.

At the time I raised the issue I was due to be on a long-haul (10+ hour) flight and I wanted to work on the document in stand-alone mode on my stock Ubuntu/pdftex system. It was on that system that I had problems.

Thanks,

Steve
