I understand there is a infinite loop, however should bash crash with SEGV? If it's out of resources (ulimit), it should be Killed by kernel instead. My versions of bash which I've tested: GNU bash, version 4.3.42(1)-release (x86_64-apple-darwin15.0.0) GNU bash, version 4.3.30(1)-release (x86_64-pc-linux-gnu) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bash/+bug/1525436/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
