Hello,

I'm sorry but GdPicture 5 is a very long time discontinued product that we do not maintain anymore.
All I have been able to find is this, from the Microsoft MSDN:

The raceOnRCWCleanup managed debugging assistant (MDA) is activated when the common language runtime (CLR) detects that a Runtime Callable Wrapper (RCW) is in use when a call to release it is made using a command such as the Marshal.ReleaseComObject method.

So it definitely looks like it is because of the ActiveX, since you are using .NET language you should definitely consider trying the latest release, the issue should be gone.
