Cute, I didn't know the voodoo to change the type of the pointer inside a shared pointer while retaining its reference counts. > > (btw, the right cast for upcasts is `static_cast`. reinterpret_cast can > return wrong results in more [[ https://godbolt.org/z/5W7rz3fKK | complicated > scenarios ]]) Huh, interesting. The names seem backwards to me, static_cast sounds like it takes the pointer you gave it and casts it to the target type, whereas reinterpret sounds like the one that figures out what the class hierarchy actually is and does the right thing, but it looks like it's the other way round. ================ Comment at: lldb/source/Target/StopInfo.cpp:805 + ThreadPlanSP step_over_wp_sp(new ThreadPlanStepOverWatchpoint( + *(thread_sp.get()), shared_from_this(), wp_sp)); + Status error; ---------------- labath wrote: > And use `static_pointer_cast<StopInfoWatchpoint>(shared_from_this())` here. > That way the casting remains confined within the origin class. I didn't know that voodoo, looks like we use it in other places, however, so I switched to doing it that way.
