I am almost certain that the following used to work just fine. However, it certainly doesn't work any more.
I have workshop materials (based on UK TUG's) which use wrappers to input a common file containing the material for slides, handouts and notes. ignorenonframetext is used to avoid having the workshop exercises appear in the slides.
Last year, I started supplementing the handouts by adding appendices. This worked great. This also worked in November. It does not, alas, work now.
MNWE:
\documentclass[ignorenonframetext]{beamer}
\begin{document}
\begin{frame}{some frame}
some frame
\end{frame}
\appendix
\section{appendix}
some stuff
\end{document}
I first get lots and lots of messages saying
Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding):
(hyperref) removing `\translate ' on input line 20.
This message is repeated numerous times, with exactly the same line number.
This is followed by numberous instances of the following message,
Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding):
(hyperref) removing `\translate ' on input line 21.
with, again, the same line number.
After a while removing \translate on lines 20 and 21, TeX gives up.
! TeX capacity exceeded, sorry [input stack size=5000].
<inserted text>
\<>-\translate
l.21
! ==> Fatal error occurred, no output PDF file produced!
What has changed and what should be changing to avoid this problem?
I am compiling with pdfTeX. I get the same error with TeX, LuaTeX or XeTeX, however.

This was a bug introduced in beamer version 3.44. For the moment this bug is fixed in the development version of beamer (and probably in release versions >= 3.50?), see the related bug report at https://github.com/josephwright/beamer/issues/464
While using https://raw.githubusercontent.com/josephwright/beamer/master/base/beamerbasesection.sty the MWE compiles fine again.
