The error occurs when casting a temporary array into a pointer and forwarding the result to a constructor. Code to reproduce : ``` #include <stdint.h> #include <iostream> #include <cstring> #define DEFAULT_DST_MAC ((uint8_t[6]) { 0xFC, 0xFC, 0x48, 0, 0, 0}) class foo{ public: foo(const uint8_t new_mac[6]){ std::cout << new_mac << std::endl; memcpy(&this->mac, new_mac, 6); } private: uint8_t mac[6]; }; int main(){ foo f((uint8_t*)DEFAULT_DST_MAC); return 0; } ``` Console log for `g++ -v -c main.cpp -freport-bug -save-temps` : ``` Using built-in specs.
