[Python-modules-team] Bug#480657: python-opengl: Using glutDisplayFunc and glutKeyboardFunc causes Segmentation Fault in glutMainLoop

[Brendon Higgins]

Hi,

Some more information I've discovered about this bug:

1) A test on a friend's 32-bit PowerPC machine didn't reproduce it. (Maybe a 
64-bit issue?)

2) The following equivalent C code does not reproduce it:

#include <GL/glut.h>
#include <stdio.h>

void disFunc() {
    printf("disFunc\n");
    fflush(stdout);
}

void keyFunc(unsigned char c, int a, int b) {
    printf("keyFunc\n");
    fflush(stdout);
}

int main(int argc, char** args) {
    glutInit(&argc, args);
    glutInitDisplayMode(GLUT_RGB);
    glutInitWindowSize(640, 480);
    glutCreateWindow("appname");
    glutDisplayFunc(disFunc);
    glutKeyboardFunc(keyFunc);
    glutMainLoop();
    return 0;
}

That suggests that it's something about the OpenGL wrapper itself.

Peace,
Brendon
