Any chance of getting some debug symbols from libqb?

#4 should be in _log_dcs_new_cs(), I do not see another calls from
qb_log_from_external_source() which have assert() inside.
Is this pacemaker or qb problem?
I'd be inclined to claim libqb at this point.
You would wouldn't you;)
So we have had a problem with ubuntu having some strange linking/stripping
that has caused some problems with libqb logging.
So to confirm (if this is a reproducible bug) rebuild with:
./configure ac_cv_link_attribute_section=no
I'll do.
This seems to be reproducible and happens 1-2 times per day.
OS is Centos6 x86_64 (latest updates)

log_dcs.c:70 is assert(rc == 0);
So, qb_array_index() returns 0
Couldn't that be some integer overflow?
