[New-bugs-announce] [issue27660] Replace size_t with Py_ssize_t as the type of local variable in list_resize

[Xiang Zhang]

New submission from Xiang Zhang:

In list_resize, new_allocated is of type size_t but I think don't have to be now since it finally have to assign back to self->allocated which is of type Py_ssize_t. With Py_ssize_t, we can check some overflows in the first overflow check and don't need the second overflow check.
