Hi, I have an issue with some KDE4 code (built against Qt 4.8.6) where a dynamic_cast fails on OS X but not on Linux (be it with gcc or clang 3.5). In a nutshell:
class D: public class C, public class B, public class A; with C inheriting QObject (ultimately), the others being "root classes". The failing cast goes like this: C *part = m_tab[0] A *a = dynamic_cast<A*>(part); If m_tab[0] were indeed a class C* the failure would be understandable, but the code's author tells me it's actually a class D*. This is only Qt related insofar as C inherits QObject, but I was hoping to get some pointers which could help me figure out what goes wrong here. Does Qt have some mechanism by which I can check the actual type of the pointer stored in m_tab[0] (evidently typeid(part).name() will tell me it's a class C) or even if it's an invalid pointer? Running through valgrind didn't teach me anything. Would the debugger in Qt Creator allow me to follow what happens during that dynamic_cast?
