Hi Brian For some reason, now when I start the profiler (memory or perf.) ANTS hangs for a few seconds, then dies. I narrowed that problem down to my running ANTS unders a Windows XP Limited User Account. If I run ANTS under an admin account, I get different behavior: the app being profiled instantly dies. Do you want me to enable logs and resend the logs while running under an admin account? / comments

Great news guys, I spent some time to get a way to reproduce this "bad class token"/BadImageFormatException bug. The project is a simple little C# WinForms app that reproduces the problem. Run the app by itself, it works fine. Run the app under the performance profiler and Red Gate Profiler crashes. Here's the repro test case: Bad Class Token repro test case.zip p.s. Tom, I'll take you up on that free Ants Profiler offer. :-) / comments

Tom, I've updated this post which links to a working repro case. (Direct repro case download is here) That previous repro case didn't repro because I forgot to include the .pdb for the problematic dll! :-) / comments

viper, this same error happened to us as well, see http://red-gate.com/messageboard/viewtopic.php?t=2525 For us, it always is happening when we copy a generic list to an array, so I'm wondering if that's the same for you, or if it's 2 seperate issues in the profiler. / comments

Never mind that previous post, here's a link to a repro case that shows it: Bad Class Token.zip. When running the above project under the ants profiler, click the big button, and the error will be thrown. / comments

Update: after further profiling, it seems this bug is still occurring in v2.7. I've looked into where the BadImageFormatException is getting thrown, and I've found it's being thrown in the same place: in a call to the ConvertToArray method. If I delete the pdb files for my application prior to profiling, it works. Of course, no methods are then instrumented, so that's hardly a work-around. Since I cannot, at this time, send you the application causing the problem, and since I can't seem to get a reproducible test case going, is there some way you guys could give me a special build with some verbose logging to help track down the problem? I'd really like to solve this one. It'd be in the best interest of both myself and Red Gate to have this problem solved. / comments

Guys, I've got a reproducible test case for you. See the end of this post for more info and for the repro case download. p.s. this bug is still occurring in 2.7.1 -- this has been plaguing us for months, so I'd love to have it fixed! Thanks. / comments

Hi guys I'm getting this same error upon starting my app under the profiler. Here's the error info & stack trace: 8/21/2006 10:11:21 AM. An error of type System.BadImageFormatException occurred: Error message: Bad class token. Error stack trace: at MyCompany.Collections.Algorithms.ConvertToArray[TReturn,TItem](IEnumerable`1 items, Converter`2 converter) at MyCompany.MyApp.Client.ServerCommunication.ClientDataReader.ReadUser(String name, String password) in C:\Documents and Settings\Judah Himango\My Documents\Visual Studio\Projects\Judah\MyCompany.MyApp.Client\ServerCommunication\ClientDataReader.cs:line 630 at MyCompany.MyApp.Client.ServerCommunication.LoginManager.Login(String userName, String password) in C:\Documents and Settings\Judah Himango\My Documents\Visual Studio\Projects\Judah\MyCompany.MyApp.Client\ServerCommunication\RemoteLogin.cs:line 132 at MyCompany.MyApp.Client.LoginForm.LoginUser(LoginArgs args) in C:\Documents and Settings\Judah Himango\My Documents\Visual Studio\Projects\Judah\MyCompany.MyApp.Client\ServerCommunication\LoginForm.cs:line 386 at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.PrivateProcessMessage(RuntimeMethodHandle md, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink) As you can see, this happened in the Algorithms.ConvertToArray method. That method is a simple method that converts any generic IEnumerable to an array. Here's the code snippet for that method: public static TReturn[] ConvertToArray<TReturn, TItem>(IEnumerable<TItem> items, Converter<TItem, TReturn> converter) { TReturn[] retVal = new TReturn[Algorithms.Count<TItem>(items)]; int i = 0; foreach (TItem item in items) { retVal[i++] = converter(item); } return retVal; } Algorithms.Count is a method that simply counts the number of items in a generic IEnumerable by doing a foreach over the elements, incrementing an integer each iteration. So this time the error happened when converting a generic IEnumerable to an array. It previously occurred (see the first post above) when converting a generic IList to an array. It seems the profiler is having a hard time on this. / comments
