             Bug #: 56299

           Summary: Dependent lambda expression breaks explicit template

                    instantiation

    Classification: Unclassified

         Component: c++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: ers.tr...@gmail.com





The following code produces an internal compiler error:



template<class T>

class Foo

{

    void process(Foo m);    

    void bar()

    {

        [this] { process(Foo()); }();

    }

};



template class Foo<int>;
