Hello to all. As the e server is down, I'm sending this report to this
mailing list.
I think there's a memory leak in eet when openssl is used as cipher engine.
I wrote a small test case, which is attached, as well the output of the
executable in valgrind (--tool=memcheck and --leak-check=full).
I'm using eet 1.7.1 and openssl 1.0.1c.
