Since you didn't post all of your code but rather a code snippet, if I had to guess I would say you are trying to read a gobject that is NULL and for that reason you are getting the segmentation fault. Try running your code using valgrind line by line to see where the error occurs and adjust accordingly. To learn how to use valgrind whatch this.

  • rest is same as the default breakout programe

  • On line 160 you use detectCollision(window, ball) but earlier instead of ball you use circle.
