\begin{frame}
  \frametitle{Outline}
  \begin{enumerate}
  \item Crashes
  \item Debugging things that misbehave 
  \end{enumerate}
\end{frame}

\begin{frame}{The Problem}
  Software
  \begin{itemize}
  \item<1-> crashes,
  \item<2-> calculates the wrong results,
  \item<3-> or just makes your Mars orbiter crash directly onto the planet.
  \end{itemize}
\end{frame}

\begin{frame}{In \GR, things are especially hard}
  \begin{itemize}
  \item \GR is inherently multithreaded
  \item there's the whole Python/C++/SWIG fun thing
    \item oh, and by the way, we do things at a couple
      \si{\mega\sample\per\second}
  \end{itemize}
\end{frame}

\begin{frame}{Crashes / Segfaults}
  Looks like this:\bigskip

  \only<1>{\includegraphics[width=\textwidth]{segfaultcmd}}\only<2>{\includegraphics[width=\textwidth]{coredumped}}\bigskip


  \begin{itemize}
  \item Your process just ``sees'' the memory mapped into its own, isolated
    memory space.
  \item Access to memory that is not mapped, your OS gets called by a CPU interrupt
    (typically)
  \item Your OS gets a little cross with you, and kills your process
  \end{itemize}
\end{frame}

\begin{frame}{Core Dumps}
  \begin{itemize}
  \item Basically: The memory of your process the moment it crashed, saved to a
    file (Plus: State of CPU registers, and a bit of info on the state of the
    process)
  \item useful for post-mortem diagnosis
    \item but: looking through a representation of a process mem space with a
      hex editor is no fun
      \item \textbf{[Enter] Debuggers}
  \end{itemize}
\end{frame}
\begin{frame}
  \frametitle{GDB -- The \textbf{G}NU \textbf{D}e\textbf{b}ugger}
  \begin{itemize}
  \item<1-> Needs to know which executable we're dealing with
  \item<1-> takes a core dump (wiki link on title page)
    \item <2-> or a live process, actually!
    \end{itemize}
