Description Dan Davis 2004-11-11 23:09:11 UTC 
Description of problem:
  net ads join fails with a segmentation fault on x86_64 systems.
  The failure occurs fairly late in the process - the computer 
  account has already been created in Active Directory, etc.
  SELinux is disabled, as is iptables.  The problem does not occur
  on FC2 on i386.  I don't yet have any FC2 x86_64 or FC3 i386
  systems.

Version-Release number of selected component (if applicable):
  Since the backtrace shows that /usr/bin/net is calling into
  openldap, I'll give you both, from my most yum updated system.

  samba-client-3.0.8-0.pre1.3
  openldap-2.2.13-2

How reproducible:
  Configure winbind on an FC3 x86_64 box, and join the new computer
  to the domain once names are established.

Stack trace:

Program received signal SIGSEGV, Segmentation fault.

Comment 2 Dan Davis 2004-11-12 19:38:58 UTC 
Just one more note - the samba-3.0.8 tarball directly from samba.org
doesn't have this problem.  I haven't investigated the diffs and will
not patch, since I can now continue with my work.

Let me know, when I no longer need to compile the samba-3.0.8 tarball
directly.  My employer's workstations update to FC3 only after this
problem is fixed.
Comment 3 Charles Liebow 2005-01-07 01:57:54 UTC 
3.0.8 also segfaults in rhel4 beta 2 at same point using winbind..

I just got (FC current with generic kernel 2.6.12):
