Custom AnalyzeCSharp WhereSymbol causing ArgumentNullException #276
Description
I have a custom AnalyzeCSharp implementation to produce customised pages for a number of classes. This uses WhereSymbol to filter to the specific classes. However, this has recently started throwing an exception for some classes. I'm unsure which classes or what changes to the source being analysed caused this, as the error does not indicate which file or class is causing the error.
