+Yes, please provide more info about the qtsharp version you're compiling
+and where to get it.
+Dietmar already fixed a bug in deadce, please test if mini from cvs
+works for you now.
+While compiling qtsharp 0.6 I found a bug that may be close to the
+last issue your report, though you don't tell us what kind of code is
+at line 335 of QtSupport.cs.
+Anyway, the test file is:
+public class Item {
+
+	internal Item ()  {}
+
+	~Item ()
+	{
+	}
+}
+
+This compile correctly for me unless inlining is enabled.
+The error looks like:
+GC Warning: Out of Memory!  Returning NIL!
+Exception caught by the compiler while compiling:
+   Block that caused the problem begin at: /tmp/item.cs: (7)
+
+Unhandled Exception: System.NullReferenceException: A null value was
+found where an object instance was required
