[Mono-dev] SEGV in mono_class_is_assignable_from in gmcs

Running gmcs under the mono debugger got me further: I was able to find 
the code causing the issue.

There were two methods in a class that had the form:

   private static XXX<T> FindRelevant<T>(XXX<T>[] candidates);
   private static object FindRelevant<T>(IComparable[] candidates);

And the type XXX is 'public class XXX<T> : IComparable<XXX<T>>'. These 
FindRelevant methods are called in various places in the containing 
class, always with an argument of type XXX<T>[]. Renaming the latter 
method fixed this issue, but I'll still try to make a concise test case.
