Hi, I am baffled by a couple of bugs I noticed running Mono (embedded in R) on a Linux box.
* Issues occur on a Debian64. Occurs with Mono 2.10.8 as well as when running on a recompiled mono using the 3.0.5 tag. * Annoyingly, the issue disappears if I try to diagnose by attaching to the MonoDevelop soft debugger * No issues running the same (c/c#) code with Mono 3.0.x on Windows. I'd appreciate guru's insights/suggestions for methods to nail this fickle bug, which is a serious blocker for my purposes. ============================== fuller repro information is at : http://r2clr.codeplex.com/workitem/47 Scenario: R ==> Embedded Mono / c code ==> C# glue code The call from the R interpreter: clrGetStaticMembers(obj_or_typename='Rclr.ClrFacade') fails if called a third time in succession. There is no side effect that could explain why. Subsequent calls will all succeed. Key lines of code, where types == null seems *completely* impossible. Type[] types = getTypes(arguments); // Array.ConvertAll(arguments, (x => (x == null ? typeof(object) : x.GetType()))) var method = classType.GetMethod(methodName, bindingFlags, null, types, null); Exception thrown in the method invocation Argument cannot be null. Parameter name: types at System.Type.GetMethod (System.String name, BindingFlags bindingAttr, System.Reflection.Binder binder, CallingConventions callConvention, System.Type[] types, System.Reflection.ParameterModifier[] modifiers) [0x00000] in <filename unknown>:0 _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
