Hi,

(I've also reported this problem as a Debian bug:
http://bugs.debian.org/724724)

The following document causes pdflatex or latex to hang:
----------------------->8
\documentclass{exam}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\begin{document}
\begin{questions}
\question[2] Test
\end{questions}
\end{document}
----------------------->8
It also hangs if I replace french with german.
It does not hang if I replace '\question[2]' with '\question' (2 is
supposed to be the number of points for that question.

latex output:
----------------------->8
