Stackoverflow Exception when processing ManagedReferenceDocuments

[josullivan]

Unable to build the doc site for a single project even though YAML files are being generated

Minimal repro steps:

1. Download, install and initialize Docfx 1.8 (but also happens with 1.7.x)
2. Point at single project in local Git repo in docfx.json
3. Run docfx spagent/docfx.json --serve

Expected to see the documentation site available at http://localhost:8080

Instead see a Stackoverflow Exception when building:
Info: [Build Document.TocDocumentProcessor]Building 3 file(s) in TocDocumentProcessor(BuildTocDocument)...
Info: [Build Document.ManagedReferenceDocumentProcessor]Building 134 file(s) in ManagedReferenceDocumentProcessor(BuildM
anagedReferenceDocument=>ApplyOverwriteDocumentForMref=>FillReferenceInformation)...

Process is terminated due to StackOverflowException in mscorlib.

A significant number of YAML docs are created in the api folder but no html docs generated

Any chance for us to take a look at a repo that can repro the issue?

Took us a while to get minimal repro as below where circular references cause this StackOverflowException.
`

  public class Program
  {
        static void Main(string[] args)
       {

       }

       /// <seealso cref="Program.B"/>
       public int A()
       {
          return 0;
       }

       /// <seealso cref="Program.A"/>
       public int B()
       {
           return 0;
       }
  }

@josullivan It has been fixed in DocFX 1.9.
