It's good if we have a meeting then.

Regarding openssl issues, I’ve discussed possible meeting time with Martin last month and he seemed positive.

Hi,

[ruby-core:61823] [ruby-trunk - Bug #9683] Segmentation fault when using default proc feature in ruby Hash object

From: nobu@...
Date: 2014-04-03 06:38:40 UTC
List: ruby-core #61823
Issue #9683 has been updated by Nobuyoshi Nakada.


There are two stacks, VM stack and machine stack.
> def foo; foo end
causes VM stack overflow, but recursive default proc causes machine stack overflow.
The former is detected by the VM, so no dirty pages is used.

Your patch prevents infinite recursion before it actually occurs, and would be more effective.
However, there can be other recursion calls, I'd want the way to fix them before applying it.
