Description Andrew Kornilov 2004-07-18 17:44:30 MSD

После очередного обновления несколько месяцев назад в zsh проявился глюк
(вероятно, связано с обновлением glibc ): при выборе практически всех идущих в
пакете prompt он падает в segfault. Например, prompt elite2 и прочее. Работает
всего несколько, например clint.

Comment 1 at@altlinux.org 2004-08-17 07:32:19 MSD

$ autoload -U promptinit;promptinit prompt elite2
$ prompt elite2
(at@solemn)(10241/pts)(07:31am:08/17/04)-
(%:~)- rpm -q zsh
zsh-4.2.0-alt1

Comment 2 Andrey Rahmatullin 2004-08-23 19:35:44 MSD

У меня подтверждается.
zsh-4.2.0-alt1

Comment 3 Dmitry Alexeyev 2004-08-23 20:32:09 MSD

подтверждается при настройках zsh по умолчанию, zsh-4.2.0-alt1

Comment 7 Andrey Rahmatullin 2004-08-30 08:08:56 MSD

После обновления до 4.2.1-alt1 падения прекратились.

Comment 8 at@altlinux.org 2005-01-15 03:21:13 MSK

Тогда fixed.
