Amaury Forgeot d'Arc <amaur...@gmail.com> added the comment: Did you see a compiler warning? Indeed, this function (mmap.move) decodes its arguments with: PyArg_ParseTuple(args, "kkk:move", &dest, &src, &cnt) This looks wrong to me: these three numbers should be Py_ssize_t, and decoded with "nnn".
An example of wrong behavior (on win32): >>> m = mmap.mmap(-1, 500) >>> m.move(2**32, 10, 4) # Should throw a ValueError ---------- nosy: +amaury.forgeotdarc stage: -> needs patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11697> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
