Hi GCC developers:
Assume I have a class:
Class FOO
{
Public:
void* operator new(size_t size);
void* operator new(size_t size, const std::nothrow_t &) noexcept;
void operator delete(void *doomed,size_t size);
void* operator new [](size_t size);
void operator delete [](void* object);
static void NewMemPool();
static void DeleteMemPool();
}
These operator new/delete will get a buffer from a mempool created by
NewMemPool and return a buffer to the pool.
Now if I have stmt without first call NewMemPool() :
std::shared_ptr<FOO> p(new FOO());
the program will crash.
However if I just call this directly
auto& p = std::make_shared<FOO>(); // I did not call NewMemPool yet.
My program is happy.
Should std::make_shared call my class operator new also? What’s the concept
behind std::make_shared?
Warm Regards.
