[Solved] System.AccessViolationException: The process was terminated due to an unhandled exception

Hi,

I have a webservice which is have a .NET Dll and this .NET DLL have third party dll which is having un managed code. 

And this third party dll is causing issue on one system only on rest of the server it is working fine. 

Here is the link of that dll.

To replicate I create a console application and use that dll. It is working fine there but not with webservice. 

Error:
