### Describe the bug, including details regarding any error messages,
version, and platform.
Hi, I'm experimenting a weird behavior for the equal kernel, when using it
to compare boolean values.
```golang
package main
import (
"context"
"fmt"
"log"
"github.com/apache/arrow-go/v18/arrow/array"
"github.com/apache/arrow-go/v18/arrow/compute"
"github.com/apache/arrow-go/v18/arrow/memory"
)
func main() {
ctx := context.Background()
pool := memory.NewGoAllocator()
n := 5 // number of elements in the array
// --- Build first Boolean array filled with false ---
bldr1 := array.NewBooleanBuilder(pool)
defer bldr1.Release()
for i := 0; i < n; i++ {
bldr1.Append(false)
}
arr1 := bldr1.NewBooleanArray()
defer arr1.Release()
// --- Build second Boolean array filled with false ---
bldr2 := array.NewBooleanBuilder(pool)
defer bldr2.Release()
for i := 0; i < n; i++ {
bldr2.Append(false)
}
arr2 := bldr2.NewBooleanArray()
defer arr2.Release()
// Wrap arrays as compute.Datum
datum1 := compute.NewDatum(arr1)
datum2 := compute.NewDatum(arr2)
// --- Call equal kernel ---
resDatum, err := compute.CallFunction(ctx, "equal", nil, datum1, datum2)
if err != nil {
log.Fatal(err)
}
defer resDatum.Release()
// Convert result Datum to BooleanArray
resArr := resDatum.(*compute.ArrayDatum).MakeArray().(*array.Boolean)
defer resArr.Release()
// Print element-wise comparison
for i := 0; i < int(resArr.Len()); i++ {
fmt.Printf("arr1[%d] == arr2[%d] -> %v\n", i, i,
resArr.Value(i))
}
}
```
I would expect this snippet to print true for all result values, but it
print false.
Is this expected behavior? Am I missing something?
