Hi! When I used property accessor in script, my application stopped. Is this bug? //----------------------------------------------------------- // AngelScript script code class Vector3 { float x; float y; float z; }; class Hoge { const Vector3 get_pos()const { return mPos; } const Vector3 foo()const { return pos; } Vector3 mPos; }; void main() { Hoge h; const Vector3 vec = h.foo(); } //----------------------------------------------------------- Version: AngelScript r564(Debug Build Version) Compiler: MSVC8 Calltrace: GameProject.exe!asCArray<asCScriptFunction *>::operator[](unsigned int index=0) Line 147 + 0x6 Bytes C++ GameProject.exe!asCContext::CallInterfaceMethod(asCScriptFunction * func=0x0a8e1058) Line 1254 + 0x15 Bytes C++ GameProject.exe!asCContext::ExecuteNext() Line 2790 C++ GameProject.exe!asCContext::Execute() Line 1004 + 0x8 Bytes C++ GameProject.exe!base::ags::ContextHandle::execute() Line 104 + 0x23 Bytes C++ GameProject.exe!app::scene::SceneASTest::onSceneStart() Line 67 C++ GameProject.exe!app::Application::beginSceneProcess() Line 191 + 0x23 Bytes C++ GameProject.exe!app::Application::execute() Line 99 + 0xc Bytes C++ GameProject.exe!`anonymous namespace'::t_executeApplication() Line 50 + 0xb Bytes C++ GameProject.exe!app::EntryPoint::run() Line 73 C++ GameProject.exe!wmain(int __formal=1, int __formal=1) Line 16 C++ GameProject.exe!__tmainCRTStartup() Line 594 + 0x19 Bytes C GameProject.exe!wmainCRTStartup() Line 414 C

I wasn't able to reproduce this.

Would you mind giving revision 566 a try? The problem may have been fixed already.

Thank you for your reply.
I tried r566 , but my application stopped.

I created another sample code.


-----------------------------------------------------------
class Vector3
{
float x;
float y;
float z;
};

class Hoge
{
const Vector3 get_pos() { return mPos; }
const Vector3 foo() { return pos; }
const Vector3 zoo() { return get_pos(); }
Vector3 mPos;
};


void main()
{
Hoge h;
Vector3 vec;
vec = h.zoo(); // ok
vec = h.foo(); // runtime exception
}
-----------------------------------------------------------


I found difference of foo and zoo in bytecode.

Is this correct?

For some reason this doesn't crash for me, but thanks to you I identified and fixed the problem anyway.

You'll find the fix in the SVN rev 567.
