Disable use_only_ruby_free_at_exit in ruby_memcheck #2865

Closed peterzhu2118 closed 4 months ago

peterzhu2118 commented 4 months ago

After upgrading to ruby_memcheck 3.0.0, on Ruby >= 3.4.0, it disables the heuristics in favor of using RUBY_FREE_AT_EXIT. This caused the issues below to start showing up on CI. This commit changes it to use the original heuristics even for versions that support RUBY_FREE_AT_EXIT.
