how much gil leak pointer

For instance, consider a pointer to a base class (such as PayOff) being assigned to a derived class object address via a reference. If the object that the pointer is pointing to is deleted, and the destructor is not set to virtual, then the base class destructor will be called instead of the derived class destructor. This can lead to a memory leak.

  • Unexpected memory management behavior Issue #1056

    My specific issue with the drop behaviour is that checking a thread-local is not zero cost, and if the GIL isnt held it leads to unbounded memory growth, and potentially a permanent memory leak if the GIL is never re-acquired. The alternative (acquiring the GIL) is significantly slower than checking the not zero cost thread-local.

  • Tutorial - Boost.GIL 1.0 documentation

    GIL uses here a special step iterator class whose size is 8 bytes - it contains a raw C pointer and a step. Its operator[] multiplies the index by its step. The above version of y_gradient , however, is much slower (easily an order of magnitude slower) than x_gradient because of the memory access pattern; traversing an image vertically results

    Raw pointers (sometimes referred to as legacy pointers, or C pointers) provide bare-bones pointer behavior and are a common source of bugs and memory leaks. Raw pointers provide no means for keeping track of ownership of the resource and developers must call delete manually to ensure they are not creating a memory leak.

So, in the example above, it does not matter if the function scope is left through the return statement, at the end of the function or even through an exception: The unique_ptr< destructor is always called and therefore the object (int in the example) always deleted.
