+I am reopening this bug, because while I tried to confirm this bug, I
+found a new problem with the attached sources, which I built like this:
+
+mcs -debug Program.cs -r:log4net.dll
+
+Notice that when it crashes it is not possible to examine the value of
+the 'buckets' instance variable, the debugger reports: 
+
+ERROR: Cannot evaluate expression `buckets'
