This way, the website will display only the part's that fit your specific model. If ordering online, please make sure to choose your Year, Make and Model from the vehicle selector. If ordering over the phone, please let your Porsche Parts Specialist know of any modifications to your car that change it from it's stock form. This could happen because of an obvious code bug, or a complicated scenario of race condition in multi-threading environments.Easy ReturnsRETURNS & EXCHANGESIt is our main objective to guarantee your 100% satisfaction.The only way for this satisfaction guarantee to work, however, is if two situations are met:1) We must provide you with quality parts that fit your car correctly.2) You must provide accurate Year, Make and Model details when you place your order. The Derived class destructor reset the vptr points to the Base class vtable, which has the pure virtual function, so when we call the virtual function, it actually calls into the pure virutal ones. The pointer which points to deleted Derived.The Derived object is deleted, but somehow the pointer is.A Derived object is created, and the pointer (as Base class) is.I ran into the scenario that the pure virtual functions gets called because of destroyed objects, Len Holgate already have a very nice answer, I would like (Note you can also call _set_purecall_handler() to install your handler in some versions of MSVC). I have a handler that can provide a stack trace of where the purecall happened see here: for more details. Once you have control you can do something more useful than the standard handler. This gives YOU control of what happens when a purecall is detected. You do this by providing your own function with this signature: int _cdecl _purecall(void)Īnd linking it before you link the runtime library. To help with debugging these kinds of problems you can, in various versions of MSVC, replace the runtime library's purecall handler. The thing about these kinds of purecall is that it's often less easy to fathom out what's going on as a check for the 'usual suspects' of virtual calls in ctor and dtor will come up clean. It's possibly more likely if you're using referenced counted interfaces and you have a ref count bug or if you have an object use/object destruction race condition in a multi-threaded program. Obviously this is a pretty bad thing to try and do but if you're working with abstract classes as interfaces and you mess up then it's something that you might see. As well as the standard case of calling a virtual function from the constructor or destructor of an object with pure virtual functions you can also get a pure virtual function call (on MSVC at least) if you call a virtual function after the object has been destroyed.
