Error: libc++abi.dylib`vtable for __cxxabiv1::__si_class_type_info

cocos2d-x C++
#1

I’m building a game with cocos2d-x for iOS 6/7 (Using Xcode 5 and iOS SDK 7.0), and started introducing some patterns that exploit inheritance, and I ran into this exception.

libc++abi.dylib`vtable for __cxxabiv1::__si_class_type_info:
0x284a540:  addb   %al, (%eax)
0x284a542:  addb   %al, (%eax)
0x284a544:  jo     0x284a4eb                 ; vtable for __cxxabiv1::__libcxxabi::__void + 91
0x284a546:  testb  (%edx), %al
0x284a548:  lesl   2(%edx,%eax,4), %ebx
0x284a54c:  movl   $2046984796, %edx
0x284a551:  popl   %esp

The code looks this:

    for (auto enemyItr = EnemyQueue::getEnemyContainer().begin(); enemyItr != EnemyQueue::getEnemyContainer().end(); ++enemyItr)
            {
                EnemyCharacter *enemyCharacter = dynamic_cast(*enemyItr);
                CCSprite *enemy = enemyCharacter->getCharacterSprite(); // inhertiance introduced to EnemyCharacter class

                CCRect enemyMeleeRect = enemy->boundingBox(); //-> exception
}

I thought this is a linker error, and tried including libstdc++ “Link Binary with Libraries”. I also tried including “-lstdc++” in Other Linker flags as well, but the exception persists.

Has anyone run into this issue?

I noticed this happens when you declare callback functions as virtual. I was hoping to extend them, in a class hierarchy. Is there a possible design of doing so?
