Product: gcc Version: 4.8.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: libremax90 at gmail dot com The following C++11 code won't compile on GCC 4.8.2 while clang++ will accept it without a warning. In the following test case, GCC seems to check Base's default constructor visibility in the test function's context, where the templates are instantiated. class Base { protected: template<class... TArgs> Base(TArgs...) {} // Uncomment to workaround //Base() {} }; class Class : public Base { public: template<class... TArgs> Class(TArgs... args) : Base { args... } {} // Another workaround: //Class() {} }; void test() { Class{}; } Here is `g++ -v`'s output: Using built-in specs.
