https://bugzilla.novell.com/show_bug.cgi?id=223296 ------- Comment #6 from jjoy@novell.com 2006-11-23 04:56 MST ------- This looks like a gtk library issue. We could not find this issue when the binary (ZenInstaller.exe) was built on a suse 9.3 setup. However when we try to build zen-updater on OpenSuSE 10.2 (I have Beta 2) we are able to see this issue.. We are trying to see what exactly is causing this problem..

https://bugzilla.novell.com/show_bug.cgi?id=223296 ------- Comment #10 from jpr@novell.com 2006-11-23 09:28 MST ------- Fix submitted, see the patch included. Try: http://w3.suse.de/~jpr/zen-updater-7.1.100-31.i586.rpm Issue seems to be in this code: EventBox eb = new EventBox (); eb.Add (l); eb.ButtonPressEvent += delegate (object sender, ButtonPressEventArgs e) { Label tl = eb.Child as Label; filterType = (FilterType) Enum.Parse (typeof (FilterType), tl.Text); this.GdkWindow.Cursor = normalCursor; searchEntry.Text = String.Empty; filteredModel.Refilter (); DisplayFilterLabels (); }; The variable eb was null inside the delegate, I don't know if this is a compiler error not propogating eb into the delegate or a compiler error not erroring out because eb is out of scope. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

This is the test case I used: ==== using System; public class EventBox { public event EventHandler ButtonPressEvent; public void ButtonPressed (EventArgs args) { if (ButtonPressEvent != null) ButtonPressEvent (this, args); } public void Test () { } } class X { static void Main () { EventBox eb = new EventBox (); eb.Test (); eb.ButtonPressEvent += delegate (object sender, EventArgs e) { Console.WriteLine (eb != null); }; eb.ButtonPressed (null); } } ==== That works with all three versions of mcs/gmcs I have (1.2, latest SVN and my development tree). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I thought there was an additional compiler bug. So, the workaround from #10 should fix the problem. JP, correct? In that case let's close this bug...
