I'm trying to bind a C++ function which takes a script-array param. Following the example in the string add-on's utils, I've got the following (in C++):

namespace
{
    void Foo(const CScriptArray& arr, MyClass* sprite)
    {}
}

scriptEngine.RegisterObjectMethod("MyClass", "void Foo(const array<Vector2> &in)", asFUNCTION(Foo), asCALL_CDECL_OBJLAST);

I'm getting a segfault at the following location:

	asSSystemFunctionInterface &operator=(const asSSystemFunctionInterface &in)
	{
		func               = in.func;

Am I registering the function incorrectly? I'm using: SDK 2.28.1 WIP - 2014/01/23

Thank you very much.

UPDATE:

Please note that if I specify the array param as: const array<string> &in, I don't experience the issue. Vector2 above is an application-registered value type.

Thank you very much for the quick reply.

I'm trying revision 1823 and I'm still seeing the issue. (I confirmed via http://sourceforge.net/p/angelscript/code/1821/ that I seem to have the updated code in as_scriptengine.cpp).

It looks like the fix in revision 1821 was in RegisterObjectProperty() and I'm in RegisterObjectMethod(). (Don't know if that's helpful)

UPDATE:

I'm also consistently experiencing the crash with the param as: const array<float> &in. Though it's repeatedly OK with: const array<string> &in

It appears that const array<mynamespace::Vector2> &in also works fine when registered as a global function.

This is the backtrace (for registering the param as: const array<float> &in):

In GenerateNewTemplateFunction(), the failure is in assigning to sysFuncIntf:

// TODO: template: Must be careful when instanciating templates for garbage collected types
//                 If the template hasn't been registered with the behaviours, it shouldn't
//                 permit instanciation of garbage collected types that in turn may refer to
//                 this instance.

func2->inOutFlags = func->inOutFlags;
func2->isReadOnly = func->isReadOnly;
func2->objectType = ot;
func2->sysFuncIntf = asNEW(asSSystemFunctionInterface)(*func->sysFuncIntf);

func->name is "factstub".

func->sysFuncIntf is null. So *func->sysFuncIntf is creating a bad reference (?).

Requested file emailed to you. I had tried to make the above line conditional (to avoid the bad assignment) and then I ran into another issue in:

asCScriptFunction *asCScriptEngine::GenerateTemplateFactoryStub(asCObjectType *templateType, asCObjectType *ot, int factoryId)
{
    ....

    // Skip the first parameter as this is the object type pointer that the stub will add
func->parameterTypes.SetLength(factory->parameterTypes.GetLength()-1);
}

factory->parameterTypes.GetLength() was 0, so SetLength() tried to do a massive Allocate() which failed.
