WPF Application crashing with Exception Code c0000005

Jul 15, 2014 at 12:26 PM
I am converting a large number of PDFs to PNGs in a multi-threaded WPF application that gets document locations from a database and after conversion, I put the location of the converted document into another database. The program runs fine until after some time (around an hour maybe) it just crashes with an Exception Code c0000005.

The following is the details of the exception:

I am using the Magick.NET x64 version and .NET 4. It doesn't seem to be on a particular file since I was able to convert all the remaining documents (after the crash) in another process.

I have never got this error in Visual Studio's debugging mode, only when I run the application without VS. In the VS, I sometimes get another error saying 'Attempted to read or write protected memory'

Could this be the Magick.NET library?

I would first advise you to upgrade to the latest version of Magick.NET. Can you reproduce the issue when you disable OpenCL? (MagickNET.UseOpenCL = false)

I get the following error on MagickNET.UseOpenCL = false :

An exception of type 'System.TypeInitializationException' occurred in Magick.NET-x64.dll but was not handled in user code.
Additional information: The type initializer for 'ImageMagick.MagickNET' threw an exception.

Can you try again with this development build: https://www.dropbox.com/sh/2omlarb120mecwz/AAB_d_JPd4X_ubmW0UlVfmX_a.

I can't access dropbox or any other file sharing utilities at my work place so I can't get the build. Is there any other way I could get the file?

Contact me trough CodePlex and I will get your email. I can e-mail it to you.

The problem still exists with the development build. However, it ran for around three hours this time.

Update: Just started another process that crashed not long after it started with the same exception.
