Memory leak when duplicating identhash [Bug #20145] Before this commit, both copy_compare_by_id and hash_copy will create a copy of the ST table, so the ST table created in copy_compare_by_id will be leaked. h = { 1 => 2 }.compare_by_identity 10.times do 1_000_000.times do h.select { false } end puts `ps -o rss= -p #{$$}` end Before: 110736 204352 300272 395520 460704 476736 542000 604704 682624 770528 After: 15504 16048 16144 16256 16320 16320 16752 16752 16752 16752 --- hash.c | 10 +++++++++- test/ruby/test_hash.rb | 10 ++++++++++ 2 files changed, 19 insertions(+), 1 deletion(-)
