In order to properly do that, we should remove all try/catch blocks in QtCore and replace with scoped pointers and scoped values. We should let the destructors handle the cleanup. Turning exceptions off may or may not get you the backtrace. It may also get you a std::terminate or a crash. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
