Bug report: exception while disassembling

Hi.

I'm running .NET Reflector 5.1.4.0 and want to disassemble this assembly I've got from DevExpress. But it keeps failing at a particular point with a System.InvalidOperationException. Here's the details from Reflector, followed by the method's IL as extracted by ILDASM:

Translation failure in 'DevExpress.XtraGrid.Views.Grid.ViewInfo.GridViewInfo.CalcColumnsDrawInfo() : Void' in 'DevExpress.XtraGrid.v7.3, Version=7.3.12.0, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1'.

System.InvalidOperationException


InnerException:

Block statement count of zero during condition expression translation.

    Hi Mike,

    Thanks for the bug report. These are normally caused by an obfuscator creating IL which cannot be expressed in C#. We will have a look and verify that this is the case.

    If it is unfortunately there is often very little we can do to create some sort of meaningful C# representation when the control flow has been altered so radically.

    Thanks James.

    That could be.

    But I think it is unlikely because the rest of the assemblies that I Reflector'ed came out just fine. If they were going to obfuscate the IL, then surely they would have done it in more places than just 1 method (the rest of the class in the affected assembly AND ALL the other classes in that assembly came out perfectly, and the C# code is perfectly legible)?

    Mike,

    I will see if I can get a copy of that assembly and try and understand why its happening with just that method.

    If you can let me have your e-mail address, I'll send it to you. Can you get my address from the forum database, or should I insert it into a message?

    I'm having the same problem with another assembly. This one was built in Mono but shows up fine, nothing is obfuscated. I can actually view the offending classes in their most part, except for a few methods that crash Reflector.
    FileDisassembler and FileGenerator both hang, I guess they can't do more than what Reflector gives them.

    I sent a bug report, the highlight being: 
    Translation failure in 'UnityEditor.GUITemp.DoListView(Rect, ListViewState, Int32[]) : ListViewElementsEnumerator' in 'UnityEditor, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

System.InvalidOperationException

InnerException:

Invalid branching statement for condition expression with target offset 00CB.

    I don't feel comfortable sending the DLL, but if you have the courage you can download a demo of the product here: http://unity3d.com/unity/download
    It's a Mac app (Windows version coming soon, yay!), but I think some Windows archivers can open dmg files... :roll:
    Extract the app, locate the DLL, browse to UnityEditor.GUITemp.DoListView to reproduce the crash.

    Is there a way to read the actual CLR (if that even means anything)? I mean the app works so obviously the DLL is valid, it's just C# translation that fails...

    Answering my own question: to view IL, simply change the language in Reflector's options.
    So I guess "target offset 00CB" is the instruction number? I see stloc.1, "pops the current value from the top of the evaluation stack and stores it in the local variable list at index 1"... hmm, doesn't mean a thing to me :D !

    Maybe the disassembler could fail more gracefully, ie display the valid lines before/after the offending instruction?

    I get the same exception looking at the GetUrl method of the System.Web.UI.CompositeScriptReference class in the System.Web.Extensions assembly from .NET 3.5 SP1:

    System.InvalidOperationException

    InnerException:

    Block statement count of zero during condition expression translation.

    System.InvalidOperationException
