BC++ and VC++ already have implemented this facility. See C++ standard draft: ------- Part of C++ standard draft (exception handling related part) --- If the object or array was allocated in a new-expression and the new-expression does not contain a new-placement, the deallocation function (_basic.stc.dynamic.deallocation_, _class.free_) is called to free the storage occupied by the object; the deallocation function is chosen as specified in _expr.new_. If the object or array was allocated in a new-expression and the new-expression contains a new-placement, the storage occupied by the object is deallocated only if an appropriate placement operator delete is found, as specified in _expr.new_. --------------- ------------------------------------------------------- ----------------------------------------------------------------------- At 21:55 04.09.97 +0000, you wrote: >Hi! > >I'm well aware g++ has bugs in its exception handling.
