I have a few questions

on which line does it crash? you can use the angelScript debugger to step through code and figure out exactly where it's crashing.

I'll step-through it, and get back to you on this. fairly certain it's:
Data @D = cast<Data@>(A.GetBuffer());

though.

As for the sizeof() operator, I'm not (entirely) sure, but why not overload a function in the C++ side like so?

This won't work, as the class is dependent on the script. what i want to achieve is to allow each script to need only the external memory it needs to work. in the past i've built a storage container for this, but it meant doing look-ups to map variables/pointers. i'm hoping to find a way that would allow me to map a point in memory directly to a class.

edit: It's happening with this line:
A.GetBuffer();

i'm registering it like so:
ScriptEngine->RegisterObjectMethod("Obj", "ref GetBuffer()", asMETHOD(Obj, GetBuffer), asCALL_THISCALL);

edit2:
this is the crash dialog i get:

Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

line 174: as_callfunc_x86.cpp
