This minimal example makes my latex/pdflatex from MiKTeX (or TeX Live of a colleague) crash:
\documentclass{revtex4-1}
\usepackage{dblfloatfix}
\begin{document}
Hello World!
\begin{figure}
\end{figure}
\end{document}
It writes out several 100 MB of log files until I force quit it. Why is this? Not using dblfloatfix, or using a different document class solves the problem, but not my use case.
dblfloatfixis simply incompatible withrevtex4-1because the class redefines very thoroughly thefigureenvironment. – egreg May 15 '13 at 22:48
