Latest stunnel is broken

[John Klos <john%ziaspace.com@localhost>]

Hi,

I've recently been trying to update stunnel from 4.20nb3 to 
stunnel-4.24nb1 on an amd64 system running -current. No matter what I try, 
I can't get it to work, and I'm afraid to break other machines.

With the same, working configuration file, I see five instances of stunnel 
(four owned by root, one by nobody) instead of just one owned by nobody. I 
see connections coming in, but nothing happens, and the connections 
eventually die on their own.

Without changing the config file, I can downgrade from 4.24 to 4.20, 
launch, and everything works fine.

Here's a debug output of a connection:

Here's a working connection from 4.20:

Does anyone have any clues about what broke? Is anyone else successfully 
using stunnel 4.24?

Thanks,
