Hi, I'm developing a cartography application (http://maperitive.net) in C# and I plan to use IronPython as a scripting extension of the application. I've been successfully using IronPython for several months and most users don't have any issues with it, but a small percentage of users is having problems.
With the help from one of them I managed to dig out the exception stack trace. The exception occurs while calling the Python.CreateEngine() method: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Failed to load language 'IronPython 2.6.2': Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at Microsoft.Scripting.Actions.TopNamespaceTracker.PublishComTypes(Assembly interopAssembly) at IronPython.Runtime.Binding.PythonBinder.DomainManager_AssemblyLoaded(Object sender, AssemblyLoadedEventArgs e) at IronPython.Runtime.Binding.PythonBinder..ctor(PythonContext pythonContext, CodeContext context) at IronPython.Runtime.PythonContext..ctor(ScriptDomainManager manager, IDictionary`2 options) --- End of inner exception stack trace --- at Microsoft.Scripting.Runtime.LanguageConfiguration.LoadLanguageContext(ScriptDomainManager domainManager, Boolean& alreadyLoaded) at Microsoft.Scripting.Runtime.DlrConfiguration.LoadLanguageContext(ScriptDomainManager manager, LanguageConfiguration config) at Microsoft.Scripting.Runtime.DlrConfiguration.TryLoadLanguage(ScriptDomainManager manager, AssemblyQualifiedTypeName providerName, LanguageContext& language) at Microsoft.Scripting.Runtime.ScriptDomainManager.GetLanguageByTypeName(String providerAssemblyQualifiedTypeName) at Microsoft.Scripting.Hosting.ScriptRuntime.GetEngineByTypeName(String assemblyQualifiedTypeName) at IronPython.Hosting.Python.GetEngine(ScriptRuntime runtime) I couldn't find anything on Google that would be related to this. Some info about the user's environment: - Win7 64bit - Using .NET 2.0-3.5 (not 4.0) - IronPython is not installed in GAC, the app uses assemblies locally on the disk (v 2.6.2) - The user runs the application as an ordinary user (not administrator) I use Win7 64bit myself, but I didn't have any such problems and I cannot reproduce this problem on any of my machines (Win7, Ubuntu). Thanks for any help, Igor Brejc _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org http://mail.python.org/mailman/listinfo/ironpython-users
