[MacRuby-devel] That bus error: Reproducible and with all gl calls!

And also with a simple C program:
~/tmp% cat e.c
#include <OpenGL/gl.h>

int main()
{
   glMatrixMode(GL_PROJECTION);
   return 0;
}
~/tmp% cat e.c
#include <OpenGL/gl.h>

int main()
{
   glMatrixMode(GL_PROJECTION);
   return 0;
}
~/tmp% gcc -framework OpenGL -o e e.c
~/tmp% ./e
zsh: bus error  ./e

So as Laurent said, it's probably just an initialization problem.
