Lua interpreter made iPod mini reboot

[Astorga]

I was making a test in iPod mini using a lua file, and it made my DAP reboots.
Here's the code:

Code: [Select]

function sayhello(seconds)
  local message = string.format("Hello from LUA for %d seconds", 5)
  rb.splash(seconds, message)
end

-- Drawn an X on the screen
rb.lcd_clear_display()
rb.lcd_drawline(0, 0, rb.LCD_WIDTH, rb.LCD_HEIGHT)
rb.lcd_drawline(rb.LCD_WIDTH, 0, 0, rb.LCD_HEIGHT)
rb.lcd_update()

local seconds = 500
rb.lcd_putsxy(10,10,"teste1")
rb.lcd_update()
function test()
	while true do
		rb.lcd_clear_display()
		local but = rb.button_get(true)
		--[[if but == 2 then rb.lcd_putsxy(10,30,"Menu")
		elseif but == 4 then rb.lcd_putsxy(10,30,"Play")
		elseif but == 8 then rb.lcd_putsxy(10,30,"Right")
		elseif but == 16 then rb.lcd_putsxy(10,30,"Left")
		else rb.lcd_putsxy(10,30,"----") end]]--
		rb.lcd_putsxy(10,30,but)
		rb.lcd_update()
		if but == 1 then break end
	end
end
test()
sayhello(seconds)

I'm using current build. That happens when I was taking note of the key values, so when I saw the screen, it was already rebooting.

Edit: apart of that, the buttons constants are the same for all iPods?

Edit2: The fact that I forgot a call to rb.yield() explains that?
