-----------------------------------------------------------
As per [~shinrich] suggestions, I've been running with this minor change to see
if we get something different (since x == -1 in frame #7):
{code}

Debug("ssl-shutdown", "SSL_shutdown %s", (ret) ? "success" : "failed");

I don't think this is necessarily the right solution, but interestingly enough,
with this, I'm now seeing another assertion (not sure if this is different, or
still related to the same, it is totally different);
