You aren't reading my replies.   I read and replied to each one of the  
following.   I'll clarify again.

Yes, and I confirmed that this isn't the problem.  There's no IPv6  
address in /etc/hosts, nor does this host use DNS at all.   No way for  
it to derive "::1" from its name anywhere.  (and I don't use localhost  
anywhere, but likewise localhost has no ::1 entry)

For which I pointed out that a problem which affects only Bacula will  
be referred back to here.   Why would it not be?  "Bacula is  
crashing..." because they will immediately (and rightly so) send me  
right back to these lists.

I did.  I found 6 references to it, most of which don't appear  
related, and none of which identified either a bug or a fix.  Any  
actual problem tends to have numerous reports -- 6 unrelated entries  
spanning 10 years that mention this function doesn't make much of a  
case for anything.

If I overlooked a clear problem related to this, or a patch related to  
this, I'm happy to re-read.  But I read them all carefully, and all  
related messages in those mailing lists, and I saw nothing that  
indicated a clear bug or even a similar problem.   Not a single one of  
them relates to freebsd 7.2 and only one relates to freebsd 7 at all.   
Most of them seriously predate FreeBSD 6.3.   And guess, what -- I've  
run bacula on every version from 4.4 up to 6.3 without any drama.

So yes, there very well could be a FreeBSD related bug here.   But  
without any more information, short of reading the code myself from  
scratch and building test cases, I have no place to start.

I'm sorry, I haven't had time to get a gdb dump.  It didn't appear  
likely to be received well.   If you'll accept it, I'll prioritize it.

Well if you were to describe what it's doing, it might help me  
identify things I could investigate which could further isolate,  
identify or resolve the bug.  Give me somewhere useful to investigate.

No, I have read everything you've said.  I responded to each in turn,  
and have done everything you suggested other than walk over to the  
freebsd mailing lists and say "Bacula is crashing -- help" because  
they will immediately (and rightly so) suggest I contact you.
