Hi

On Win32, Linux, MaxOs work fine, bug on - ARM( iPad )

after call C++ function, and pass in here asOBJ_VALUE type( my string's ), he create a copy, but not call destructor

simple code

void startGame(){
   MyStr m1;
   TestMyStrLeak( m1 );
}

C++

int con_count = 0;
int des_count = 0;

class MyStr{
public:
    MyStr(){
        std::cout << "CONSTR: " << ++con_count << "\n";
    }
    MyStr( const MyStr &other ){
        std::cout << "CONSTR Ohter: " << ++con_count << "\n";
    }
    ~MyStr(){
        std::cout << "DESTR: " << ++des_count << "\n";
    }
    static void Construct(MyStr *thisPointer){
        new(thisPointer) MyStr();
    }
    static void CopyConstruct(const MyStr &other, MyStr *thisPointer){
        new(thisPointer) MyStr(other);
    }
    static void Destruct(MyStr *thisPointer){
        thisPointer->~MyStr();
    }
};

void MemLeakMyStr( MyStr my_str ){
    std::cout << "L\n";
}

void RegMyStr( asIScriptEngine *en ){
    int r;
    r=en->RegisterObjectType("MyStr", sizeof(MyStr), asOBJ_VALUE | asOBJ_APP_CLASS_CD ); nu_assert( r >= 0 );
    r=en->RegisterObjectBehaviour("MyStr", asBEHAVE_CONSTRUCT,  "void f()",             asFUNCTION(MyStr::Construct), asCALL_CDECL_OBJLAST); nu_assert( r >= 0 );
    r=en->RegisterObjectBehaviour("MyStr", asBEHAVE_CONSTRUCT,  "void f(const MyStr &)",asFUNCTION(MyStr::CopyConstruct), asCALL_CDECL_OBJLAST); nu_assert( r >= 0 );
    r=en->RegisterObjectBehaviour("MyStr", asBEHAVE_DESTRUCT,   "void f()",              asFUNCTION(MyStr::Destruct),  asCALL_CDECL_OBJLAST); nu_assert( r >= 0 );
    r=en->RegisterGlobalFunction( "void TestMyStrLeak(MyStr name )",asFUNCTION(MemLeakMyStr),asCALL_CDECL);nu_assert(r>=0);
}

output:

CONSTR: 1

CONSTR Ohter: 2

L

DESTR: 1

Engine flags:

engine->SetEngineProperty(asEP_ALWAYS_IMPL_DEFAULT_CONSTRUCT, false);

engine->SetEngineProperty(asEP_ALLOW_UNSAFE_REFERENCES, true);

engine->SetEngineProperty( asEP_ALLOW_IMPLICIT_HANDLE_TYPES, true );

engine->SetEngineProperty(asEP_AUTO_GARBAGE_COLLECT, true);

engine->SetEngineProperty( asEP_DISALLOW_VALUE_ASSIGN_FOR_REF_TYPE, true );

engine->SetEngineProperty(asEP_COPY_SCRIPT_SECTIONS, true);

With ref type ( MyStr & name ) or generic type, work fine

Use last svn version

Can you try removing the following define from the as_config.h file?

#define AS_CALLEE_DESTROY_OBJ_BY_VAL

You'll find it in the area with the configuration for GNUC, APPLE, ARM (halfway into the file).

Let me know if that fixes the memory leak.

yes, its resolve problem

Thanks for confirming it. I've checked in the fix in revision 1818.
