[New-bugs-announce] [issue5386] mmap can crash with write_byte

[Hirokazu Yamamoto]

New submission from Hirokazu Yamamoto <ocean-city at m2.ccsnet.ne.jp>:

mmap.write_byte doesn't check buffer size, so it can cause crash like
bellow.

import mmap
m = mmap.mmap(-1, 1)
for i in xrange(10000): # enough?
    print i
    m.write_byte('1') # crash

The patch is in r69945.
