----------------------------------------
(Original bug report: <https://github.com/socketry/async/issues/224>)
The `IO::Buffer` implementation incorrectly calls `rb_fiber_scheduler_io_write` with the
`size_t`s converted to `VALUE`s:
https://github.com/ruby/ruby/blob/400ccb16eefe4e21c4e3eacab4fd0f208fc5e151/…
But that function expects `size_t`s:
https://github.com/ruby/ruby/blob/400ccb16eefe4e21c4e3eacab4fd0f208fc5e151/…
(And probably the same for the other scheduler methods + data types.)
Fixed by <https://github.com/ruby/ruby/pull/7593>.
