Angelscript does not seem to be able to properly call the copy constructor of a simple POD type that is being returned from a registered global function for some reason. When it does call the copy constructor, the this pointer of the new object is null, but the input variable has a valid address from the c++ function. I'm using version 2.31.0 WIP.

The problem seems to be around line 1097 in as_callfunc_x86.cpp:

// Copy return value from EAX:EDX
lea  ecx, retQW
mov  [ecx], eax
mov  4[ecx], edx

My C++ code:

PointF Instance::GetBodyPos()
{
	PointF pos;

	if (pBody)
	{
		pos.Set( pBody->GetPosition().x*MTP_RATIO, pBody->GetPosition().y*MTP_RATIO);
	}
	
	return pos; //<------------- Crashes on return. pos gets passed in correctly though
}
