Bad access in virtual methods (iOS ARM)

I getting EXC_BAD_ACCESS in virtual methods when i run program on iPad. It happens only if method returns registered data type and if method have virtual definition in base class. My code: [source lang="cpp"] virtual my_type Base::method() = 0; ... my_type Derived::method() { ... this->field = 10; // EXC_BAD_ACCESS ... } [/source] If i replace code above with: [source lang="cpp"] virtual void Base::method(my_type &res) = 0; ... void Derived::method(my_type &res) { ... this->field = 10; // OK ... } [/source] problem will disappear. I have this problem only on ios device. i've tested my code on windows, osx and iphone simulator - all is ok. If i replace 'my_type' to 'int' all is ok as well. It looks like calling of virtual methods with wrong object. So, what it can be? ps: as version - 2.25.0
