Summary | 0003600: Attempted to read or write protected memory when resizing window | ||||
Description | I'm getting a System.AccessViolationException when, under certain circumstances, resizing the MainWindow of my application. My question is, what can I do to find the root cause of the exception. The stack trace tells me that Noesis.App.dll throws the exception but I have no other information as to what is causing it. The exception: Exception thrown: 'System.AccessViolationException' in Noesis.App.dll Attempted to read or write protected memory. This is often an indication that other memory is corrupt. The stack trace: Noesis.App.dll!NoesisApp.Window.Render(double time) Noesis.App.dll!NoesisApp.Application.Run.AnonymousMethod__51_0(NoesisApp.Display d) Noesis.App.Displays.Win32.dll!NoesisApp.Win32Display.EnterMessageLoop(bool runInBackground) Noesis.App.dll!NoesisApp.Application.Run() I cannot reproduce this in a simpler scenario and I also cannot reproduce it using one of the samples. | ||||

Can you attach the crash minidump too so we can debug it? | |
I'm unable to attach the file directly to the note, the upload never completes. I don't think size is the problem, it's a 600Kb zipped file. Here is a link where you can get the minidump from: https://we.tl/t-BBxKuHJYwd | |
It is crashing updating some geometries in the render tree, but I can't figure out the origin of the problem. Are you able to reproduce this crash using one of our samples? If not, would it be possible to get a minimal project where I can reprocude it? Thanks a lot for your help. |
|
I can't reproduce the exception using the samples. I could try to create a minimal project that reproduces the exception but it would really help if I had a hint of what the real error is. Right now I only know that resizing the window triggers it. Could you provide more info on the exception on your end? | |
The crash is happening invalidating (in the render thread) a child geometry of a GeometryGroup, probably the Data of a Path shape element. But I'm not able to determine if that geometry was deleted or if it is something else. |
|
Thank you for the error information, it pointed me to the right direction. I have a reproducible case, although the exception does not always throw in the minimal project I am attaching. However, I am always getting an error in the output and the window turns black. The error: [NOESIS/E] <memory>(10,70): Invalid token Here is a link to a minimal test project: https://we.tl/t-1Hqa7x5JvQ Thank you |
|
The error message "[NOESIS/E] <memory>(10,70): Invalid token" corresponds to an issue already solved (0003311). And the black screens gets solved if you update all the Noesis nuget packages to the latest 3.2.4 version (you were mixing 3.2.2 with older 3.1.7 in packages.config). Could you please try to upgrade to the latest version and see if everything works as expected? |
|
You are absolutely right. But my real app uses v3.2.4 and still crashes. So I had to try harder to reproduce this and I hope I have a case. Please try running again. The crash happens when resizing the window but the second tab must not be focused. The following steps always crash the app for me: 1. Run the app and select the second tab 2. Let it run for a few seconds (you will see some random data running in the chart) 3. Go back to the first tab 4. Try to resize the window. You'll most probably need to resize a few times before the app crashes Thanks for all your help |
|
Thank you for the new project, I was able to reproduce it and I can now debug it. |
|
Hi, I found the source of the problem and have generated a patched library, could you please try it? https://drive.google.com/file/d/1-w7F2LvvhRr383W_Ad8eNsBeBrWy8Jpu/view?usp=sharing |
|
Thank you for the patch. I tested with my real application and it works for the Windows target. The Android target is still having the same issue but I guess the patched dll is only meant to work for Windows. | |
