Subject Why is qpid::sys::ssl::shutdownNSS being called in a global destructor?
Date Tue, 01 Dec 2009 21:34:50 GMT
I'm getting this core dump on exit from the cluster_tests in a cmake build:

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.

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)
