Having quite a bit of trouble trying to debug Rhino crashes as a result of unholy things that I’m doing in Grasshopper (a lot of flow control, custom classes, selective expire, event listening, etc).
If I fire up Grasshopper in a debug session I get no kind of exception on crash, it just fails hard. This last time, I had VS open (not attached) and the JIT debugger offered me the opportunity to attach to VS, and I got this cryptic message:
Unhandled exception at 0x00007FFFD0DB843B (ntdll.dll) in Rhino.exe: 0xC0000374: A heap has been corrupted (parameters: 0x00007FFFD0E1C6E0). occurred
This tends to happen on adding geometry to the document and I think is related to custom classes that are created and mutated in a C# component at runtime (tree access). I’m wondering if wrapping the C# code into a proper custom component would be worth the work, not sure if there are memory leaks in the C# component environment?
Any tips on how to get more information on this crash would be appreciated. I’d provide more information but I don’t know where to start.
Thanks,
Marc
