A dangling pointer is a pointer that points to invalid data or to data which is not valid anymore, for example: Class *object = new Class (); Class *object2 = object; delete object; object = nullptr; // now object2 points to something which is not valid anymore. This can occur even in stack allocated objects: WebMay 25, 2024 · Segmentation fault when using a shared_ptr. You should never create shared_ptr from an ordinary pointer as you do here: shared_ptr (&e) This tries to free the ParticleEmitter twice. Once as the vector holding the ParticleEmitter objects goes out of scope, and once as the shared_ptr goes out of scope. c++.
