I have overloaded the new and delete operator, then I found this in the source code: // note: this should really be a member of the load_ptr function // below but some compilers still complain about this. template<class T> struct heap_allocator { #if 0 // note: this fails on msvc 7.0 and gcc 3.2 template <class U, U x> struct test; typedef char* yes; typedef int* no; template <class U> yes has_op_new(U*, test<void* (*)(std::size_t), &U::operator new>* = 0); no has_op_new(...); template<class U> T * new_operator(U); T * new_operator(yes){ return (T::operator new)(sizeof(T)); } T * new_operator(no){ return static_cast<T *>(operator new(sizeof(T))); } static T * invoke(){ return new_operator(has_op_new(static_cast<T *>(NULL))); } #else // while this doesn't handle operator new overload for class T static T * invoke(){ return static_cast<T *>(operator new(sizeof(T))); } #endif }; If I am using a msvc that this does not fail on, is there anything wrong with implementing this code, or will I get a bunch of errors or "hidden" bugs? Also, are there any plans on implementing this in a future release(I am guessing it is a work in progress issue)? Thanks in advance. /Jacob Holm
