It seems that attempts to mmap a region of size zero causes mmap to return zero. Is this a bug?
Since it doesn't return -1, it looks like success, but of course dereferencing this NULL pointer causes a crash.
Why would you dereference it if you didn't specify any memory? It seems to me that this is valid kernel behavior, and that the program has the bug.
