[GitHub] [arrow-rs] jyericlin commented on issue #2874: Pointer freed error when deallocating ArrayData with shared memory buffer

   Thank you very much @tustvold for the suggestions. I appreciate it. The `Buffer::from_custom_allocation` works well. The only thing I had to modify is to create a dummy object as the allocation instead of `Arc::new(shmem)` as the shmem contains a `*mut u8` which can not be sent between threads safely. Then I can manage the shared memory (creation and free) manually.
