Exception e0000008, but app is not BrowserSubprocess

[assopri]

While testing my app I get app crash with Cefsharp Offscreen version. In debug mode it also showing me this window:

I suppose, it can be related to out of memory exception. I just noticed, that exception code is "e0000008", however app name is MYAPP and module with error is kernelbase.dll.

I found that e0000008 - is typical exception for BrowserSubprocess, so could that be somehow related with Cefsharp? Any ideas how to go deeper?

My OS is Windows7 64x , VS 2019 installed. I use Offscreen Cefsharp version, .NET 4.5.2 . Cef version is 90.6.50.0

Is your application x64 or x86? This is often seen when the process runs out of memory. Most common when running 32bit applications (x86). 32bit applications need to be made large address aware. https://github.com/cefsharp/CefSharp/wiki/General-Usage#win32-out-of-memory

You can download the libcef.dll.pdb if the call stack originates from libcef

I'd suggest enabling crash pad if you haven't already see https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting#crash-reporting
Once you have a mini dump you can get a stack trace.

How can I analyze it now to get more details on what exactly causes the crash?

You can load the mini dump in visual studio.

the crash is causing on my app version just after processing it with ilprotector+smartassembly. Any ideas how could that happen?

I don't know what you mean by this. I've never heard of ilprotector+smartassembly

Basic instructions at https://docs.microsoft.com/en-us/visualstudio/debugger/using-dump-files?view=vs-2019#BKMK_Open_a_dump_file

Make sure to load the pdb file.

Ok, I had 4 files from the particular crash:

I loaded the first one and got the following screen:

The other dumps are looking very similar.

What can I do to find out more details? How can I make sure that I loaded pdb file, except for just checking its presence in exe folder of my app?
