Fix memory in rb_reg_search_set_match
https://.com/ruby/ruby/pull/12801 changed regexp matches to reuse the backref, which causes memory to if the original registers of the match is not freed. For example, the following script s memory: 10.times do 1_000_000.times do "aaaaaaaaaaa".gsub(/a/, "") end puts `ps -o rss= -p #{$$}` end Before: 774256 1535152 2297360 3059280 3821296 4583552 5160304 5091456 5114256 4980192 After: 12480 11440 11696 11632 11632 11760 11824 11824 11824 11888
