Summary0001173: Noesis.dll caused an Access Violation (0xc0000005) in module Noesis.dll at 0033:5ce69d0f
Description

I have a xaml where tapping a button opens another xaml by doing:
Resources.Load(System.IO.Path.GetFileNameWithoutExtension(xamlPath));
Noesis.GUI.LoadComponent(o, xamlPath);

I get the crash on 6th try of doing this.

Currently don't have a minimal project to reproduce - was hoping that the attached log/dump may give you clue.
Can test with debug noesis version if you have.

Just a clarification because what I wrote is misleading - crash is not when I try to load the new page.
I'm navigating forward and back between those 2 xamls and when the crash happens it is before the Click event of the button - I put a breakpoint inside it and it crashes before reaching it.

The crash is related with touch manipulations:

>   Noesis.dll!Noesis::Gui::TouchScreen::NewManipulationFinger(Noesis::Gui::UIElement * uiElement, const Noesis::Drawing::Point & p, unsigned int id) Line 642 C++

Noesis.dll!Noesis::Gui::TouchScreen::TouchDown(int x, int y, unsigned int id) Line 160  C++

We will investigate it.

TouchDown was a great lead!
In our project Noesis view EnableTouch/EnableMouse are disabled. We are feeding input events to Noesis by calling TouchDown/Up (both on PC and Android, no mouse down/up).

But recently we added feeding both TouchDown/Up and MouseDown/Up in 1 special case - when button is inside a scrollviewer - done as workaround for the button not getting visual pressed state when inside a scrollviewer (forum: http://www.noesisengine.com/forums/viewtopic.php?f=3&t=1210&sid=86879a9e273e156cdde74f4074dcd6f9). MouseDown/Up visually results in a pressed state, while touchdown/up not.

Now I disabled the workaround and Unity/Noesis don't crash anymore. Crash was both under Editor and Android.
