[Converted from Gnats 1496] Given the source: class baseClass { public: class Component { public: Component() {} virtual ~Component(){} }; }; class subClass : public baseClass { public: class Component : public baseClass::Component { public: Component() {} void dummy() {} }; }; int main( int argc, char * argv[] ) { subClass::Component * comp = new subClass::Component(); comp->dummy(); return(0); } gdb seg faults when trying to display subClass::Component.
