Hi all, As you may know modern C++ debuggers (GDB and LLDB) support dynamic type identification for polymorphic objects, by utilizing C++ RTTI. Unfortunately this feature does not work with Clang and GDB >= 7.x . The last compiler that worked well was G++ 6.x I've asked about this issue both on GDB and LLDB maillists. Unfortunately it's hard or impossible to fix it on debugger side.
