I don't think that has anything to do with it at all.  I did more runs, and
each one dies is a different place.  However, I noticed several dying in
free() so...

Prolly confused gdb.  It's a home grown linux system.

Anyway, I build with -DDEBUG_DMALLOC and saw something interesting.

1010658364: 81100: Dmalloc version '4.8.2' from 'http://dmalloc.com/'
1010658364: 81100: flags = 0x4e40d03, logfile '/tmp/logfile'

1010658364: 81100: heap-check: failed OVER picket-fence magic-number check: pointer '0x87f23c8' from '../leafnode-2.0b8_ma9rc1/fetchnews.c:91'

1010658364: 81100: ERROR: fence_read: failed OVER picket-fence magic-number check (err 27)

And ../leafnode-2.0b8_ma9rc1/fetchnews.c:91 is:

     89     mastr_vcat(s, spool, "/leaf.node/", server, portstr, suffix, 0);
     90
     91     res = critstrdup(mastr_str(s), "server_info");
     92     /*mastr_delete(s);*/
     93     return res;
     94 }

I commented out the mastr_delete(s) and so far it's running better.

I'm off to bed.  Check in the morning to see if it survived.
