Charles-François Natali added the comment: > If I remember correctly the problem is that some OS like linux (and probably others) do not really allocate space until something is written. If that's the case then the process may get killed later on when it writes something in the array.
Yes, it's called overcommitting, and it's a good thing. It's exactly the same thing for memory: malloc() can return non-NULL, and the process will get killed when first writing to the page in case of memory pressure. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21116> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
