Some samples cause interpreter crash on Ruby 2.3.0 #23

Closed vaiorabbit closed 8 years ago

vaiorabbit commented 8 years ago

For example,

$ ruby --version
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]
$ cd RedBook
$ ruby teapots.rb

And then pressing some keys cause :

/Users/foo/.rvm/gems/ruby-2.3.0/gems/opengl-bindings-1.5.2/lib/glfw.rb:408: [BUG] Segmentation fault at 0x0000010ff46000

I have just started investigating this problem. Any helps are welcome.

vaiorabbit commented 8 years ago

Using Fiddle::Closure may help to avoid crashing.

For example, rewrite codes like

key_callback = GLFW::create_callback(:GLFWkeyfun) do |window_handle, key, scancode, action, mods|
  case key
  when GLFW_KEY_ESCAPE
    glfwSetWindowShouldClose(window_handle, 1)
  end
end

into

GLFWkeyfun_cb_args = [Fiddle::TYPE_VOIDP, -Fiddle::TYPE_INT, -Fiddle::TYPE_INT, -Fiddle::TYPE_INT, Fiddle::TYPE_INT]
GLFWkeyfun_cb_retval = Fiddle::TYPE_VOID
key_callback = Fiddle::Closure::BlockCaller.new(GLFWkeyfun_cb_retval, GLFWkeyfun_cb_args, Fiddle::Function::DEFAULT) { |window_handle, key, scancode, action, mods|
  case key
  when GLFW_KEY_ESCAPE
    glfwSetWindowShouldClose(window_handle, 1)
  end
}

I updated glut.rb and glfw.rb at revision https://github.com/vaiorabbit/ruby-opengl/commit/ea018f3198c9ae918c680ab5bb68533567ebbc22 .
