  @AlexRu can you attach your project and logcat again?

  Hi @atilim.
  I found the problem. It was division by zero in my code. I thought that Event.MOUSE_MOVE return coordinates only then mouse move and got it.
  Shape:lineTo(-1.#IND, -1.#IND)
  Shape:endPath() --here got crash in 2.3.3 device, but it work good in 2.2 device and Gideros Windows Player.
  
  But it's interesting why the same project with same bug work different at different devices.

  @AlexRu Interesting. Maybe it's the difference between armv6 and armv7? What are the CPUs of your 2.3.3 and 2.2 devices?

  arm6 both. May be problem in operating system on 2.3.3 device. Last time it freezes sometimes.

  Most ARM processors implement division as a software intruction (this includes division by zero handling) so I guess that there is a bug in that library function and it's not throwing the exception, or the OS kernel registered a division_error trap handler to catch it and it's not handling it correctly.

  Thanks @Javi. Before, I have never thought about how the processor executes instructions. The longer I live, the more I know))
