Re: mmap bug?

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.
