Hmm, so it's failing right here:
```go
case *file.ByteArrayColumnChunkWriter:
var (
buffer = leafArr.Data().Buffers()[2]
valueBuf []byte
)
if buffer == nil {
valueBuf = []byte{}
} else {
valueBuf = buffer.Bytes()
}
data := make([]parquet.ByteArray, leafArr.Len())
```
I feel like the most likely way an invalid pointer makes it onto the stack
here is through `valueBuf`, which would be the 3rd buffer of the array, and
since we're writing byte arrays, presumably there's an Arrow binary or string
column. Is Polars perhaps somehow leaving behind an invalid pointer when
there's (say) an empty or all-null array?
