Compute crashing - "Attempted to read or write protected memory"

[mdjaere]

Rhino compute crashes while attempting to run a medium sized grasshopper definition. Rhino compute is running in a docker container on an EC2 unit. The definition solves without issues on the same instance using grasshopper manually in about 10 seconds.

Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Can you repeat this crash by testing your definition with Hops in a desktop environment?

We would need the definition to be able to do any debugging.
