glut segmentation fault

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

I hope that this program is too short to contain a bug:

#include <GL/glut.h>

int
main(int argc, char *argv[])
{
        int window;

        glutInit(&argc, argv);

        glutInitDisplayMode(GLUT_RGB);
        glutInitWindowSize(400,500);
        window = glutCreateWindow("Bug");

        return 0;
}

Compiled with this little Makefile:

PROG=bug
CPPFLAGS+=-I/usr/X11R7/include
DBG=-g -O0 -Wall
LDFLAGS+=-Wl,-R/usr/X11R7/lib -L/usr/X11R7/lib
LDADD+=-lglut -lGLU -lGL -lXi -lXmu -lX11 -lXext -lm
MKMAN=no
.include <bsd.prog.mk>

I see on a -current/amd64 sandy bridge with native X:

Go digging, or does something need updating?

Cheers,
