Firstly you need a core file that is created when stunnel crashes. There
are some things that may prevent it from being created: under linux
maximum core file size is 0 by default. Consider running
"ulimit -c unlimited" in the same shell that you will start stunnel
later (this is per process-descendants). Make sure the user that stunnel
is running as can write to the current directory it is running in.

When you get the core, type:

gdb /usr/local/bin/stunnel core
(gdb) bt

What gets output-ed is the backtrace.

For better output it whould be better if you recompile stunnel with
debugging symbols (add -g switch to the compiler).
