Memory leak when using OpenSSL

Hi everybody,

I'm using libcurl+OpenSSL in my application to do HTTPS transfers.
Everything is working great, but when my application shuts down, the MSVC++
memory tracker says that OpenSSL is leaking memory. After looking at the
sample OpenSSL applications (e.g. ssltest.c), it seems that
CRYPTO_cleanup_all_ex_data() is needed when shutting down. Adding this call
to Curl_SSL_cleanup() fixes the memory leaks. Is there a reason
CRYPTO_cleanup_all_ex_data() isn't being called?

Here's my config:
- Visual C++ 2003 (Win32)
- libcurl 7.10.7
- OpenSSL 0.9.7b

BTW, Thanks for a fantastic library!

Cheers,
Loren Kirkby
