Why could this code throw segmentation fault?:/
listeners = new vector<Listener*> ();
... /* other code */
if (listeners != NULL) {
int i = listeners->size();
}
Just because the pointer isn’t
NULLdoesn’t mean it points to a validvector<Listener*>object.Run your program through valgrind to detect memory corruption issues, and make sure that you run your code through your debugger, too.
If you still have problems, post a test that reproduces the issue (rather than little snippets of code that do not).
