Description

Similar to the memory leak fixed in https://bugs.ruby-lang.org/issues/9743 there is an issue with ossl_pkey_sign. The ruby heap usage reported through GC.stat remains very stable, while the process heap grows linearly with the number of OpenSSL::PKey::RSA sign calls.
The documentation at https://www.openssl.org/docs/crypto/EVP_SignInit.html (similar to EVP_VerifyInit) mentions that not disposing the context causes a leak.
