Beamer Presentation References slide can't allowframebreaks and have \frametitle

Question

I am writing a Beamer presentation and my references are too long for one frame. So I tried to use [allowframebreaks], but then I get the TeX capacity exceeded error if I have a \frametitle. I can have either frame breaks or the title, but not both. I am using natbib and pdflatex on ShareLaTeX.com.

Here is my code:

\documentclass[14pt, compress]{beamer}

\usetheme{m}

\usepackage{booktabs}
\usepackage[scale=2]{ccicons}
\usepackage{minted}
\usepackage{amsmath}
\usepackage{adjustbox}
\usepackage{graphicx}
\usepackage{url}
\usepackage{float}
\usepackage{setspace}
\usepackage{tikz}
\usepackage{caption}
\usepackage[super]{natbib}
\usemintedstyle{trac}

\bibliographystyle{apalike}



\title{The Prospects of D-T Nuclear Fusion as a Source of Electricity Production}
\subtitle{A Senior Seminar}
\date{23 April 2015}
\author{Kyle Reilly}
\institute{Cedarville University}



\graphicspath{{figures/}}


\begin{document}

\begin{frame}[allowframebreaks]
\frametitle{References}

\footnotesize{
\bibliography{Seminar_References.bib}
}

\end{frame}



\end{document}

Answer 1

The allowframebreaks option sometimes requires you to \protect the frametitle.

You should make the following change to your document:

\begin{frame}[allowframebreaks]
  \frametitle{\protect References} % \protect the title here

  \footnotesize{
    \bibliography{Seminar_References.bib}
  }

\end{frame}

If you want to understand more about why you need \protect, check out the discussion in What's the difference between Fragile and Robust?

Edit: Apologies, \protect doesn't have the intended effect at this level of the compilation. You could try the following work-around by editing the lines in beamerthemem.sty with the \protect command:

  281: \protect\insertframetitle%
  284: \textsc{\MakeLowercase{\protect\insertframetitle}}%

Here is a working example.
