An application trying to allocate more than that will get an error (ENOMEM). If the app doesn't detect and handle the error, it will probably crash. There are techniques that applications can use to deal with huge files such as loading smaller pieces that are needed into memory and caching out changes to a temp file. However, I have no idea if vim works that way - you would need to check the documentation and/or give it a try yourself. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
