Windows 10: UIRibbon.dll crash in my Windows app

I am developing a C# Windows Forms app that is using the UIRibbon dll through the Sunburst.WindowsForms.Ribbon package. I have been trying to track this seemingly random crash for months now, and I finally have a reproduceable way to make it happen. It seems to be happening deep inside UIRibbon.dll. The dll code is crashing on an == operator. The pointer reference ecx is not null, so it’s probably a “real” access violation. Without the source code for the dll, all I can see are symbols and x86 registers.

Before I started using UIRibbon through the Sunburst.WindowsForms.Ribbon, I was using a different WinForms ribbon library that was all managed. I didn’t like the library after spending countless days fiddling with their code to fix bugs, so I decided to migrate to something else. I should say that aside from these rare crashes, the ribbon is behaving just as it should in the app. The app is incredibly stable otherwise. It seems extremely unlikely that my app is somehow corrupting memory and always managing to hit UIRIbbon and nothing else. That was actually my first thought months ago when this first started. At this point, I am finding it difficult to believe it has something to do with the Sunburst.WindowsForms.Ribbon package, as it’s a very lightweight wrapper around the DLL. I am open to evidence to the contrary. The code is built on the Windows Ribbon for WinForms by Arik Poznanski project from several years ago.

Here’s how I can reproduce the problem 2 out of 3 times: Switch ribbon tabs and click a button which runs a blocking long-running command 2-3 seconds. While that is running, click on the original ribbon tab. When the command completes, both tabs are highlighted and the access violation occurs. I suspect blocking the UI thread is a necessary part of reproducing the bug, but that's just a hunch.

Here is the stack traces of the error:

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

all games crash!

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

DLL Missing

The problem is, that the required DLL is not actually even listed there.
There are just dozens of download adware links from the top to the bottom.
