sv.c contains this comment:
/* The change that added SV_COW_SHARED_HASH_KEYS makes the logic
when PERL_OLD_COPY_ON_WRITE is defined a little wrong.
Conceptually PERL_OLD_COPY_ON_WRITE being defined should
override SV_COW_SHARED_HASH_KEYS, because it means "always COW"
but in turn, it's somewhat dead code, never expected to go
live, but more kept as a placeholder on how to do it better
in a newer implementation. */
What is wrong with PERL_OLD_COPY_ON_WRITE? Why wouldn’t it work the way it is written?
