Debugging possible crash for bindgen-generated bindings?

Hi,

I'm trying to build a rust wrapper for the V8 JavaScript engine. When attempting to replicate the hello world example from Rust, I get an access violation every time I attempt to create a context, which does not occur when I use it from C++. Hence, I'm either doing something wrong, or there is a problem in the generated bindings.

I've combed through my code and they replicate the c++ calls as far as I can tell, except that I have to provide more params that are left out in c++ as they have default values. The layouts of the structs are also right as far as I can tell.

Is there anything else that I might be overlooking?

Start by reproducing the V8 hello world example from the linked C++ sample through the Rust wrapper, focusing on the context-creation call and the bindgen-generated bindings. Compare the Rust arguments and struct layouts with the C++ calls, then document whether the crash comes from wrapper usage or generated bindings and provide a minimal reproducer.
