[stunnel-users] stunnel 4.10 on Suse 8.2

[Ionut Turturica]

I get a segmentation fault on first connect.
To the default config, i've added the debug = 7 and foreground = yes.
I have used for comparison 2 versions 4.09 and 4.10 compiled with default  
options (./configure, make, make install)
It seems like UCONTEXT is not welcome on my machine.
