Package: samba Version: 2:4.4.5+dfsg-3+b1 Followup-For: Bug #840382 I was also hit by this bug on 2:4.4.5+dfsg-3+b1.
As a workaround downgrading libtevent0 from 0.9.31-1 to 0.9.28-1 ends the crashing and makes Samba work. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.7.0-rc3-amd64 (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=fi_FI (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash Init: sysvinit (via /sbin/init) Versions of packages samba depends on: ii adduser 3.115 ii dpkg 1.18.10 ii init-system-helpers 1.45 ii libbsd0 0.8.3-1 ii libc6 2.24-3 ii libldb1 2:1.1.27-1 ii libpam-modules 1.1.8-3.3 ii libpam-runtime 1.1.8-3.3 ii libpopt0 1.16-10 ii libpython2.7 2.7.12-3+b1 ii libtalloc2 2.1.8-1 ii libtdb1 1.3.11-2 ii libtevent0 0.9.28-1 ii libwbclient0 2:4.4.5+dfsg-3+b1 ii lsb-base 9.20160629 ii procps 2:3.3.12-2 ii python 2.7.11-2 ii python-dnspython 1.14.0-3 ii python-samba 2:4.4.5+dfsg-3+b1 pn python2.7:any <none> ii samba-common 2:4.4.5+dfsg-3 ii samba-common-bin 2:4.4.5+dfsg-3+b1 ii samba-libs 2:4.4.5+dfsg-3+b1 ii tdb-tools 1.3.11-2 ii update-inetd 4.43 Versions of packages samba recommends: ii attr 1:2.4.47-2 ii logrotate 3.8.7-2 pn samba-dsdb-modules <none> ii samba-vfs-modules 2:4.4.5+dfsg-3+b1 Versions of packages samba suggests: ii bind9 1:9.10.3.dfsg.P4-10.1 ii bind9utils 1:9.10.3.dfsg.P4-10.1 pn ctdb <none> pn ldb-tools <none> pn ntp <none> pn smbldap-tools <none> pn ufw <none> pn winbind <none> -- Configuration Files: /etc/logrotate.d/samba changed [not included] -- debconf information excluded
