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; ^ Please submit a full bug report, with preprocessed source if appropriate.
