Description Stéphane Davy 2003-10-17 07:12:13 UTC
I've tried to install Samba 3.0.0 on AIX 5.2. I have previously made a
successful install of samba 3 rc1 with ads support. With the 3.0.0 one,
everything is fine during the build and install process. But when I try to use
one or another of the samab binaries, I always have a core dump.
So, I have reduced all the compil options only to --prefix= and I have the same
I've tried the 3.0.1pre1, and it works. But I've copied my final directory to
another AIX 5.2 partition, I still have some core dumps.
I've tried the stable samba release on AIX 4.3.3... and it core dumps also.

Jim,  here's another one (AIX).
Comment 2 Jim McDonough 2003-11-05 05:28:39 UTC
Stephane, can you please include some more information here, like a backtrace,
and perhaps attach a log.  Does it coredump at startup, or only when the server
is contacted.  Which binaries coredump?  All of them, or just certain ones?
Comment 3 Stéphane Davy 2003-11-19 07:26:19 UTC
(sorry for the delay, I was on holidays)
Unfortunately, I don't have some much details to give. I can say that most of
the binaries core dump: testparm, smbclient, smbd,... NOT nmbd but don't go in
background with -D switch, NOT winbindd. smbd doesn't core dump with -V switch.
Everything have been compiled with the IBM C compiler v5, and the config is a
vanillia one (just --prefix)
The only messages I have is... Segmentation fault(coredump). I don't have a
debugging tool related to these kind of binaries, but I can send you the core
file. I'll make some new test with PRE3 version
Comment 4 Adrian van Bloois 2003-12-02 02:31:29 UTC
We have the same problem, both on AIX 4.3.2 and AIX 5.2.
Comment 5 Jim McDonough 2003-12-02 07:22:28 UTC
Adrian, do you have any more info, like a backtrace?  I'm having a hard time
getting access to an AIX box, so any more debug info that you can give would be
a great help.  debug from any program that cores would be a good start, plus any
core info, like a backtrace.

Please find attached some syslog information:
attachments #296 and #297 (smbd & nmbd dump info)
Hope this information helps to solve the problem.
Comment 9 Jim McDonough 2003-12-03 08:02:45 UTC
Adrian, is it leaving corefiles anywhere?  I'd like to see a backtrace if at all
possible.  It's possible that this is related to the messages about charset
modules not loading, but I'd like to verify it.  Thanks.

If you do have corefiles, try "dbx smbd core" (just to be safe, use the full
path to smbd) then run "where", and cut/paste the output here.
