[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

http://www.openssl.org/docs/crypto/X509_STORE_CTX_new.html によると、

X509_STORE_CTX_cleanup() internally cleans up an X509_STORE_CTX structure.
The context can then be reused with an new call to X509_STORE_CTX_init().
