Anyone ever tried to let the timer of allegro point to a object method? I
have a small snippet that compiles, but crashes when i start it.

class Oallegro
{
public:
   Oallegro(int width, int height, int bitdepth);
   ~Oallegro();
   void breathe();
   void unbreathe();
   void messagepump();
};

void Oallegro::breathe()
{
  install_int_ex(Oallegro::messagepump, MSEC_TO_TIMER(20));
}

void Oallegro::unbreathe()
{
  remove_int(Oallegro::messagepump);
}

void Oallegro::messagepump()
{
   handlemouse();
}

Everything goes wrong when messagepump() is called. When i put a simple
printf into the method, there's no problem at all. But when i do something
with variables or call one of my other (virtual) classes, the program
crashes.

Please help!
