2023-06-29Fix memory leak when copying ST tablesPeter Zhu
st_copy allocates a st_table, which is not needed for hashes since it is allocated by VWA and embedded, so this causes a memory leak. The following script demonstrates the issue: ```ruby 20.times do 100_000.times do {a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7, h: 8, i: 9} end puts `ps -o rss= -p #{$$}` end ``` Notes: Merged: https://github.com/ruby/ruby/pull/8000
