+Summary: gmcs aborts when mixing generics with anonymous delegates
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+gmcs aborts compiling code that returns an anonymous delegate for a generic
+method returning a generic delegate.
+
+Steps to reproduce the problem:
+1. Compile the attached program with gmcs: gmcs functor.cs
+2. Watch the fireworks.
+
+Actual Results:
+
+jon at balthasar:tmp$ gmcs functor.cs
+ 
+** ERROR **: file metadata.c: line 2758 (mono_type_size): assertion failed:
+(!gclass->generic_class.inst->is_open)
+aborting...
+Aborted
+
+
+Expected Results:
+
+No mono runtime error.  At minimum a useful gmcs error (if the C# code
+isn't valid, though it looks like it should be valid to me).
+
+How often does this happen? 
+
+Always.
+
+Additional Information:
+
+This can be worked around by doing the work that the anonymous delegate
+should be doing for me.  See the mono-devel-list email for a workaround:
