Debugging managed app crash

Question

I'm trying desparately to debug an application I'm trying to release. It was created on Win7 x64, and also runs fine on Win x32, but not on XP (Don't have Vista to test).

I've created a dump file by setting the _NT_SYMBOL_PATH to the directory of the application in XP, then run the debugger with: adplus -crash -pn launchmenot.exe

This creates a dump file which I've opened in Visual Studio 2008 (Having specified the directory of the application's PDBs and the MS symbol servers in VS. After VS downloads all of the symbols I just get 'There is no source code available for the current location'.

I have a feeling it could be from using the Interop.IWshRuntimeLibrary from Win7 on XP, but I really don't know.

The dump file is 107Mb, but the app itself is online here (compiled in debug mode). Could anyone point me in the right direction for finding the cause or fixing the error please?

Much appreciated. :)

Answer 1

You might have a bit more luck in wndbg -- download from the Debugging Tools for Windows page. Load the crash dump, set the symbol path and run !analyze -v to get detailed information on the crash. If you are still having problems finding the correct symbols try running !sym noisy and also the !itoldyouso command

Answer 2

Use WinDebug to analyse the dump - it can also used for managed code.

See the blog entries by Tess Ferrandez for more info.

Answer 3

Does this error message mean anything to you:

Cannot convert string 'pack://application:,,,/Resources/icon.ico' in attribute 'Icon' to object of type 'System.Windows.Media.ImageSource'. The image format is unrecognized. Error at object 'LaunchMeNot.WinUnhandledException' in markup file 'LaunchMeNot;component/winunhandledexception.xaml' Line 10 Position 46.

Edit: this last exception is actually being thrown from the unhandled exception filter and becomes fatal. There're two inner exceptions that describe the problem in more detail. It all starts off with this trace:

which clearly indicates a problem with an image resource. The embedded exceptions are:

Exception from HRESULT: 0x88982F07

wrapped in:

The image format is unrecognized.

After a bit of googling I came across this post which details a similar finding. Looks like an icon in a unrecognized format. The post goes on to suggest to remove the icons. My guess is that you could try and redo them in a compliant editor.
