I have exactly the same problem with stunnel 5.45 and 5.46 crashing on second request!
Running on Windows 10 Pro x64 1803.
I also use https to separate traffic to two different sites on the same server as the stunnel service.

Hi,
isn't annoying when you are using an old version, 5.44, and all goes fine, you notice you are outdated and then comes the problems after update? :-P
The thing is that yesterday I needed the HTTPS server so I run Stunnel 5.44 for my non-SSL app and all was fine. I updated to 5.46 just because I forgot the last time and didn't even run again because I didn't need it.
Today I used it and... I had a crash. I tested 5.45 to trace versions back, and it crashes as well. Back to 5.44 and no crash.
The crash happens when there is a reload/reconnect/multiconnect (example, 2 connections html+images) by the browser when connects to an HTTPS server.
It only happens when using a SNI service.
I've been able to trace back the log on those versions and when fails in 5.45 and 5.46 is at the time when it needs to switch to the SNI service.
(log from 5.44) SNI: requested servername: xxx SNI: matched pattern: xxx SNI: switched to service [xxx] <<<<----- BEFORE SWITCH, IT CRASHES on 5.45 and 5.46
Imagine you load https://xxx/.
The first time is fine, the second, crashes stunnel. Not happening with 5.44.
I haven't seen any change to SNI in manual so... :-?
These are the configs for the used virtual servers. Nothing has been changed, anyway:
[SSL] client = no
accept = y.y.y.1:4747 connect = y.y.y.2:443
[SSL-xxx-SNI] client = no sni = SSL:xxx
connect = y.y.y.2:443
cert = pem key = pem
Don't mind the port numbers. They aren't in conflict.
Running on Windows 2000.
