Subject: [Mono-dev] CS0584 Internal compiler error in gmcs.exe (master)

In membercache.cs.AddBaseType () line 219, if entry.Value.Count == 1, entry.Value is a MemberSpec[] which will cause the list.Add(ce) on Line 234 to fail.

Gmcs.exe fails with "CS0584: Internal compiler error: Collection is read-only" (in ecore.cs:433) when this case is encountered.

I ran across this error while compiling our code with Mono 2.9 from master today. I'm not sure how to reproduce the error, otherwise I'd have submitted a test case.
