Summary: SIMON2DOS French: SIGBUS with an early dialog on mips64el

Initial Comment:
Hi,

This happens on the -current branch of OpenBSD/loongson (which uses the mips64el architecture, LP64, little-endian, strict alignment).

I used the latest git HEAD version (00c0986562f1eb0), with the "--disable-alsa --enable-debug --disable-seq-midi --enable-sndio" configure options, CXXFLAGS set to "-O2 -pipe -g" and the following [1] [2] patches from OpenBSD ports. The compiler is g++ 4.2.1.

I'm getting a SIGBUS with SIMON2DOS French, why is triggered by doing this:
- Start a new game
- Press Escape to skip the various introduction scenes
- When you can start playing, go to the castle
- A scene with the 2 guards starts. The game crashes just after Simon says "Qui, moi ?".

Here's gdb output (with "bt full" and "bt"):

Program received signal SIGBUS, Bus error.
