            Bug ID: 65954
           Summary: gcc segfaults on the following input with a syntax
                    error
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: federl at gmail dot com
  Target Milestone: ---

g++ 4.8.2 on Ubuntu 14.04.2 LTS, 64bit throws a segmentation fault on the input
below (it contains a small typo Cicle instead of Circle). BTW, fixing the typo
also fixes the segfault...

$ cat test.cpp

namespace carta {
    namespace lib {
        class Shape {
        public:
            enum class Type { Circle, Square };
        };
    }
}

int main( int, char **)
{
    auto x = carta::lib::Shape::Type::Circle;
    carta::lib::Shape shape;
    carta::lib::Shape::Type y;
    y = shape.Type::Cicle;
    return 0;
}

$ g++ -std=c++11 test.cpp

test.cpp: In function ‘int main(int, char**)’:
test.cpp:15:21: internal compiler error: Segmentation fault
     y = shape.Type::Cicle;
                     ^
