This looks suspect to me, doing anything of any complexity in a static
destructor is dangerous, unless the NSS library specifically states that its
safe to shutdown this way.
I'd tend to agree - perhaps this should run on module unload - oh wait -
we don't have any way except static destruction to indicate module
unload.
Not sure why its affecting the cluster tests as they don't use SSL, nor why it's
happening in cmake build and not in automake build (I'm trying to get the
cluster tests running in a cmake build)
The cmake build correctly uses the -mt versions of the libs in versions
of boost that have them (the ones in fedora do, the ones in rhel don't)
whereas the autotools build always uses the non -mt versions. That could
be the difference.
However, the current checked in cluster module doesn't build with cmake,
giving undefined symbols with fedora 11/12 at least - it does work with
rhel5 though. this is related to the new(ish) boost_system lib. So this
indicates you must be testing using rhel5 which doesn't have -mt lib.
Nope, I'm testing on f11. I have cluster module & cluster_test building and
passing tests but core dumping on exit as above.
