GCC allows to get "size" parameters of functions allocating memory to emit better warning. For example, GCC 7 will detect implicit cast from signed to unsigned integer and emit a warning. https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html Example of Python functions that can benefit of this attribute: * PyMem_RawMalloc(), PyMem_RawCalloc(), PyMem_RawRealloc() * PyMem_Malloc(), PyMem_Calloc(), PyMem_Realloc() * PyObject_Malloc(), PyObject_Calloc(), PyObject_Realloc()
