lquerel opened a new issue, #14883:
URL: https://github.com/apache/arrow/issues/14883
### Describe the bug, including details regarding any error messages,
version, and platform.
All my unit tests work with the CheckedAllocator (the one used in the Arrow
Go library) but when I added the zstd compression option to the IPC writer my
tests turned red.
The issue is located in the file arrow.ipc.writer line 345 (v10.0.1).
```go
compress := func(idx int, codec compressor) error {
if p.body[idx] == nil || p.body[idx].Len() == 0 {
return nil
}
var buf bytes.Buffer
buf.Grow(codec.MaxCompressedLen(p.body[idx].Len()) +
arrow.Int64SizeBytes)
if err := binary.Write(&buf, binary.LittleEndian,
uint64(p.body[idx].Len())); err != nil {
return err
}
codec.Reset(&buf)
if _, err := codec.Write(p.body[idx].Bytes()); err != nil {
return err
}
if err := codec.Close(); err != nil {
return err
}
p.body[idx] = memory.NewBufferBytes(buf.Bytes()). <-- line 345
return nil
}
```
The previous buffer is replaced by a new one but without:
- releasing the previous one,
- and specifying the current allocator to the new buffer.
