VS2008 SP1 crashes when using the new Debugging Feature 'Enable .NET Framework source stepping' and certain library references. I have narrowed this down to one assembly in particular - Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll (version 8.0 or 9.0).
I do not know if there are more assemblies that will cause the same behavior but I know this one assembly does.
The crash info is:
Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 1023
Time: 4:49:20 PM
.NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (7A2E0F92) (0)
I also have the StackFrame and Registers info if that will help.
