• Bug#266031: zsh: occassional random(?) segfaults

    From Harri Haataja@1:229/2 to All on Mon Aug 16 14:00:17 2004

    Package: zsh
    Version: 4.0.4-33
    Severity: normal

    Every now and then zsh segfaults (and logs out ssh sessions) etc on
    several Debian hosts. This happens at least on ia32.

    Doesn't show much, but it always looks about the same IIRC. The
    segfaults usually happen when entering commands and I can't remember it
    ever dying if left alone. So perhaps it depends on input, but I can't
    tell what input.

    Are you using any strange NSS modules?
