Issue #10735 has been updated by Zachary Scott.

Status changed from Open to Assigned
Assignee set to Zachary Scott

I know you tried this with 1.9.3, but could you try to repro on trunk (and newer rubies) first?

1.9.3 will be EOL soon, and I want to make sure we fix it upstream before attempting any backports

Bug #10735: Memory leak in openssl ossl_pkey_sign
https://bugs.ruby-lang.org/issues/10735#change-50967

* Author: Viktor Vasilev
* Status: Assigned
* Priority: High
* Assignee: Zachary Scott
* ruby -v: ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
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.
