+Product: Mono: Runtime
+Version: 1.1
+OS Details: Gentoo Linux
+Status: NEW   
+Priority: Normal
+Component: misc

+TargetMilestone: ---
+Summary: Problem with events in generic classes.
+There seems to be a runtime problem with events in generic classes. Generic
+classes seem to be generated properly, but the runtime seems unable to
+actually find the event for the class after that. As a result gmcs spits
+some odd errors about the visibility of the event, etc usually, which is
+actually a result of the generated backing field being the only item with
+the name found for the class, e.g. class Foo<T> has an event "Ev", which
+results in the event and the field "Ev" created, but only the private field
+"Ev" is seen by the compiler, so it warns about it not being visible.
+I will attach a small tarball that demonstrates the problem, with both the
+non-generic and generic classes. monodis seems to show everything generated
+properly for the classes. One works compiled with gmcs, one doesn't. This
+has been tested both with mono- and mono- I've not had a
+chance to test with SVN mono.
+In trying to debug this, I think I tracked down the problem to
+mono/metadata/metadata.c:3448 in the function
+mono_metadata_events_from_typedef. The bsearch seems to fail, so no table
+indexes are returned. I don't know the runtime internals well enough to
+even begin to ponder *why* this might be the case, how to debug further, etc.
