with the stunnel4 in Debian/Stretch i am experiencing pretty regular
crashes with illegal instruction. Version is 5.50.

In Bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880659
you can see the drill down to a Lock beeing unlocked although
not locked. When i look at the code its some usage of openssl
primitives. (Unlock happens in openssl code)

I had a quick look at the changelog and this:

	"Service threads are terminated before OpenSSL cleanup to prevent occasional stunnel crashes at shutdown."

sounds a bit like the issue i am experiencing.

Can you confirm this? 

If so it means that Debian/Stretch aswell as the to be released Buster
will have the bug. (As Buster will release with 5.50)
