Finding Memory Leaks in the Ruby Ecosystem

Ruby 3.3 introduces a powerful new feature for identifying memory leaks. Over the past year we have been working on improving memory usage within Ruby and developing tools to give native extension authors more confidence in memory management.

In this talk, we will explain what memory leaks are, the impacts of memory leaks, our new feature RUBY_FREE_AT_EXIT in Ruby 3.3, and memory leaks found through this feature. In addition, we will discuss our future roadmap for Ruby 3.4 to improve this feature for native gem maintainers.
