Grasshopper

algorithmic modeling for Rhino

This is a question for developers.

I know that the clusters still have problems, but I want to consult why this happens and if there is any solution.

I have a cluster with multiple inputs with sliders. When I change the value slowly, so good, but when I do it quickly, rhino crashed.

Attached file so they can check it.

Is it a problem of cluster object? Or my definition? Could be some kind of gap in the data inputs of a component becomes too unstable? If so, could be solved with some type of gate?

Thank you.

A crash always means it's our fault, users should not be able to crash software in an ideal world.

I can repeat the crash and I get the following .NET call stack:

System::AppDomain::CurrentDomain->UnhandledException event occured

SENDER: Name:DefaultDomain
There are no context policies.


EXCEPTION: System.Runtime.InteropServices.SEHException
MESSAGE: External component has thrown an exception.
SOURCE: RhinoCommon
CALL STACK
at UnsafeNativeMethods.CRhCmnUserData_Delete(IntPtr pUserData, Boolean only_if_no_parent)
at Rhino.DocObjects.Custom.UserData.Dispose(Boolean disposing)
at Rhino.DocObjects.Custom.UserData.Finalize()

Do you also see a crash reporting window? If so, please always send in the reports, they are all collected and organised on our YouTrack system.

Thanks David, sorry but I can not post a comment with the dump file: S I dont know why...
Can you give me some advice from your experience to fix my cluster? Or is it an absolute binary mystery? ;P Do I have any other option than to remake the definition with other logic-components? Do you think I should do trial and error or you have some better idea?

It seems to be a bug in RhinoCommon, some sort of memory issue. Either we're disposing stuff too early, or in the wrong order, or perhaps it's even going wrong in the C++ part of Rhino. I'm afraid it's too far down for me to figure out.

I can offer no solutions, I'll have to put the bug on YouTrack and we'll see what Steve has to say about it.

Ok, something I will do to make it work.

Thank you very much for your assistance David :D

Hi Daniel,

I have the same problem. I am running an automation that render with vray frames of animation. But rhino crashes every time at a different frame because of the animation slider. 

I want to ask you if you have solved the problem and how.

Thank you in advance
