Package: dbus-1
Version: 0.21-1
Severity: important

When starting dbus-daemon-1 --system, it segfaults. gdb gives the
following stack:

#0  0x401a6ad1 in _nss_compat_initgroups_dyn () from
/lib/tls/libnss_compat.so.2
#1  0x401a6645 in _nss_compat_initgroups_dyn () from
/lib/tls/libnss_compat.so.2
#2  0x6200003a in ?? ()
#3  0x00000000 in ?? ()
#4  0x32313100 in ?? ()

#8  0xbfffeaac in ?? ()
#9  0x40173192 in _dl_open () from /lib/tls/libc.so.6
Previous frame inner to this frame (corrupt stack?)

though I don't know if this gives relevant information (due to last line). The
error remains if dbus-1 is built from source on my system.

This might have been fixed by

    2003-04-23  Ulrich Drepper  <drepper@redhat.com>

        * grp/initgroups.c (getgrouplist): Don't copy too much into the
        user buffer if more groups are found than fit into it.

        * nis/nss_nis/nis-initgroups.c (_nss_nis_initgroups_dyn): Use
        extend_alloca.

or

    2005-03-29  Thorsten Kukuk  <kukuk@suse.de>

        [BZ #661]
        * grp/initgroups.c (internal_getgrouplist): Check if we have
        enough space before adding the primary group to the list.

or

    2003-06-27  Thorsten Kukuk  <kukuk@suse.de>

        * nis/nss_compat/compat-initgroups.c: Don't use our own NIS/NIS+
        functions, dlopen corresponding NSS module instead.

After gotom's ping, no one responded except someone reporting the same
bug with 2.3.2, and I suspect this is the sort of bug that would make
people unhappy enough to report it when they see it.  Closing.

Please reopen if it happens again.
