| woodbrian77@gmail.com: May 24 08:28AM -0700 I started using a version of PC-BSD that uses clang 3.6 and am getting a warning about this code: template <unsigned long N = udp_packet_max> class SendBufferStack : public SendBuffer { ::std::array<char, N> ar; public: SendBufferStack () : SendBuffer(&ar[0], N) {} }; The warning is that field ar is uninitialized when used. I think that taking the address of the field should be OK. Gcc 4.9.2 and other compilers don't warn about the code. Is this a problem or is Clang off track? Thanks in advance.

The warning is quite valid: you are indeed using an uninitialised variable; formally it might even be undefined behaviour as you are calling a non-static member function of an object that is yet to be created. Why do you insist on writing ::std::foo Brian? The correct form is std::foo. /Flibble |

The correct form is std::foo. Why do you ask? Brian Ebenezer Enterprises - Heavenly code. http://webEbenezer.net |

No it isn't but calling a non-static member function, namely operator[](), on an object that doesn't yet exist is wrong. /Flibble |

If all implementations you care about support nullptr, always use nullptr and never use NULL.

Thanks to evolution we know that Abraham, Isaac, Israel, David and all other descendants of Adam never actually existed. /Flibble |
