[issue11391] mmap write segfaults if PROT_WRITE bit is not set in prot

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Patch looks mostly good. Why do you use ~PROT_WRITE instead of PROT_READ|PROT_EXEC as in your example?
(I'm unsure whether a POSIX implementation could refuse such a value)
