New Post: Problem using V8RuntimeConstraints

I'm running into a problem trying to use V8RuntimeConstraints when creating a V8ScriptEngine, and I'm not doing anything weird so I'm guessing there must be something wrong with my project. I'm posting here in case anyone else has hit this and has a suggestion.

I'm using ClearScript 5.4.0 built myself from the official download. If I don't pass in any constraints, everything works fine. With constraints, I get a System.Reflection.TargetInvocationException when V8Proxy tries to create an instance of V8ContextProxyImpl.

The details:

Code:

var constraints = new V8RuntimeConstraints();
constraints .MaxExecutableSize = 1024*1024;
constraints .MaxNewSpaceSize = 1024 * 1024;
constraints .MaxOldSpaceSize = 1024 * 1024;

var engine = new V8ScriptEngine(EngineConstraints); // Exception thrown in here

The exception:

• $exception {"Exception has been thrown by the target of an invocation."} System.Exception {System.Reflection.TargetInvocationException}
• [System.Reflection.TargetInvocationException] {"Exception has been thrown by the target of an invocation."} System.Reflection.TargetInvocationException

Seems like there's a bad pointer or something at the C++ level. I have no idea why that would be going wrong. Any ideas?
