Managed Debugging Assistant 'FatalExecutionEngineError'

Question:

I'm getting below error:

<blockquote>

Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'C:\Users\App\App.exe'. Additional Information: The runtime has encountered a fatal error. The address of the error was at 0xf5b029e1, on thread 0x72bc. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

I get the above error when i execute this statement while debugging.

LoggerHandler.Info("Executed " & iterations.ToString & " iterations on " & max_processors & " cores in " & Format((Now() - time).TotalSeconds, "0.0") & " seconds.")

Answer1:

Changing to use "Managed Compatibility Mode" is what fixed the error for me in Visual Studio 2015:

<blockquote>

Tools menu >Options > Debugging > General > "Use Managed Compatibility Mode"

</blockquote>

This <a href="https://blogs.msdn.microsoft.com/visualstudioalm/2013/10/16/switching-to-managed-compatibility-mode-in-visual-studio-2013/" rel="nofollow">Microsoft blog</a> describes what this setting does in a bit more detail.

Answer2:

This resolved my issue:

<blockquote>

Tools -> options -> <a href="https://i.stack.imgur.com/vMlA8.png" rel="nofollow">IntelliTrace</a> -> General

</blockquote>

and check "Events Only" option
