In the patch it is already there, isn't it?

That's right. I thought about it, but I don't know where the right place is.

It breaks with Segmentation fault in my smartcard-based setup. The pkey-han=
dle=20
is all we have from the engine, when client_cert_cb() is finished. Obviousl=
y=20
the ref-counting of openssl does not take the pkey-handle into account, so =
we=20
need to keep the engine_ptr for later freeing.
close_SSL() should be the right place for ENGINE_finish() and ENGINE_free()=
?
