Thanks for the report.

1. Are you able to reproduce this in one of our examples?

2. Could you please double check this is not happening with 3.1.6 ?

1. It is difficult
2. Crashes after migration to version 3.2.0b1. The Application code has not changed.

You can provide a debug version Noesis_d.dll + Noesis_d.lib + Noesis_d.pdb?

Hi, would it be possible to get your application built, so we can execute it ourselves? That way we can use a debug version of Noesis and make changes to narrow the problem.

The debug version will be enough app.exe + MinimumContent?

Yes, whatever minimum files that are needed to launch your application, and that crash on shutdown, would be enough, thanks.

Run app - start.bat

We have implemented a multi-window interface with WindowEx class.
For these purposes, we have slightly changed the code NoesisApp::D3D11RenderContext::Init()
Each window has its own NoesisApp::D3D11RenderContext but all NoesisApp::D3D11RenderContext use one Noesis::RenderDevice (singleton).
Perhaps because of this crash.

in Noesis 2 - 3.1.6 it works fine

I was able to fix the crash inside Shutdown and generated a new patched library: https://drive.google.com/file/d/1OakiKAz5w8IOMfyHR3meWPnWeKg6SbHk/view?usp=share_link

Anyway, before Shutdown was called I hit an assert while debugging caused by releasing a BaseRefCounted object that was already deleted. Adding some logs it looks it was the RenderDevice. You should verify that you are not deleting the RenderDevice object while there are Ptr still holding a reference.
And also, after Noesis Shutdown finished, some code in your Engine.dll was trying to get the name of a type (Type::GetName()) when all types were already deleted, so it was also crashing.
Let me know if you can fix those issues and then everything closes as expected.

Just a clarification, if you store the renderer in a Ptr<> it will be automatically destroyed. It is dangerous to invoke manual deletes on BaseComponent instances.

If you want to make sure the instance is being destroyed you can do something like:

int32_t refs = obj->Release();

assert(refs == 0);

Hello
Patched the build completes successfully.

The negative number of refs was due to
//mRenderer.Reset();
mRenderer->Release();
in D3D11RenderContext::Shutdown()
I did not hesitate to change Reset to Release, but I had to remove this line.

There was another problem. Leaks.
NOESIS[W]: Memory leaks detected: 4112 bytes.

The error appeared in this build.

I can't repro this in our examples. Could you isolate this because I would say, the leaks are real.

Noesis::GUI::SetFontDefaultProperties(11.f, FontWeight_Light,
FontStretch::FontStretch_Normal, FontStyle::FontStyle_Normal);

Noesis::Init();

Noesis::Shutdown();
"NOESIS[I]: Noesis Shutdown.
NOESIS[W]: Memory leaks detected: 4112 bytes."

Noesis::Init();
Noesis::GUI::SetFontDefaultProperties(11.f, FontWeight_Light,
FontStretch::FontStretch_Normal, FontStyle::FontStyle_Normal);
Noesis::Shutdown();
Refs = 0!!!! OK

The leak comes from creating symbols before the call to Noesis::Init.
We'll analyze how to improve this.

The temp workaround is calling Noesis::GUI::SetFontDefaultProperties after Noesis::GUI::Init

Ok, thanks.
