Pure Virtual function called Error

[Ghanashyam]

I am using the COM object in .NET C# Client and I am getting an error "R6025
Pure Virtual function called".While running the application in the debugger
also I noticed the error but call stack did not provide any clue.It pointed
me to few system libraries.Any help in this regard will be of great help.
Thanks.

Not enough information to conclude anything, sorry. There's an error in the
implementation of your COM object, or you're passing it invalid arguments,
but beyond that it's impossible to say what's what. See

When I am using a VB6.0/C++ client for that COM object,everything goes
well.Only this happens when it is a .NET client.Using VS 2008 I could not
figure out exactly which COM call causes the issue.The call stack leads to
..NET system call.Though it is reproducible but it is quite inconsistent.That
gives an impression in some race condition such error occurs.Tried using
DebugDiag from Microsoft in analyzing the crash dump but it did not help much.
