             Bug #: 56692

           Summary: [4.8 Regression] [C++11] Segmentation fault when

                    calling static/non-static overloaded function from

                    lambda

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: c++

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

        ReportedBy: b...@mm.beanwood.com





The following causes an "Internal compiler error: Segmentation fault" in GCC

4.8.0 when compiled with 'g++ -std=c++11':



struct Class {

        void f () { }

        static void f (int) { }

};



int main ()

{

        [] () { Class::f(0); };

}



This does not segfault in 4.7.2.  Removing the non-static f declaration

prevents the segfault.



gcc was compiled with no configure arguments. The system is i686-pc-linux-gnu. 

Here's the complete error message, including stack trace:



t.c: In lambda function:

t.c:8:17: internal compiler error: Segmentation fault

  [] () { Class::f(0); };
