>Description:
The 'smbd' daemon from net/samba35 (3.5.11 from HEAD of pkgsrc) crashes
on startup on sparc platform (SPARCstation 5, 85MHz 256MB RAM).  The
following is recorded in "/var/log/samba/log.smbd":

Contrary to the logfile's claim, no core dump is written anywhere.

Attempting to run smbd via 'gdb' produces an unresponsive terminal session.
The output of "ps ax" shows zombie processes for 'uname' and 'tr' as a
result of starting 'smbd'.  The gdb process otherwise responds to signals.

>How-To-Repeat:
Start with pkgsrc-2011Q2, update net/samba35 to HEAD.
Set PKG_OPTIONS.samba=-cups -ldap -ads -winbind
Build net/samba35 on/for sparc.

Install and attempt to run resulting 'smbd' from net/samba35 on sparc.

 As of 19 July 2012, NetBSD-6.0_BETA2, and pkgsrc-2012Q2, a problem
 similar to that originally reported occurs with samba-3.6.5.

 Updated configuration information:

 Before digging into how to get the package to compile with debugging
 symbols, I went back and built each of net/samba{,3{5,3,0}} versions
 in pkgsrc-2012Q2 to see if it was something version-dependent.

 They all fail identically with the same messages upon trying to obtain
 a backtrace from 'gdb'.

 This would seem to indicate a systemic problem, or one influenced by
 ideosyncracies of the target architecture.

 I'll focus on the front-line samba (3.6.5) (and maybe 4.x in wip) and
 try to get something with symbols to look at.

 I'm using net/samba30 on sparc/solaris10 for ages.
 One/two years ago I had similar trouble after updating net/samba30, even 
 simple commands like "net user" didn't work anymore.
 In my case, it was related to a compiler update (SolarisStudio12.1 -> 
 OracleStudio12.2). Now I'm compiling net/samba30 with lang/gcc44.

 NetBSD-5 is EOL and more recent samba (3.6.25) runs properly on sparc
 (7.0_STABLE).

 This PR may be closed.  Thanks.
