Hi @pitrou , I have fixed the bug and tested the code with some manual test
cases in a main function.
But I'm having some trouble writing the test case for this fix. Below is the
unit test code. The unit test code is crashing (with segmentation fault) in
`ScalarExecutor::EmitResult()` after executing the current span. I'd appreciate
any help.
```cpp
// in scalar_validity_test.cc
TEST_F(TestBooleanValidityKernels, TrueUnlessNullOnREE) {
auto run_ends = ArrayFromJSON(arrow::int32(), "[1, 4, 9, 10]");
auto values = ArrayFromJSON(arrow::int32(), "[1,null,4,null]");
EXPECT_OK_AND_ASSIGN(auto z, RunEndEncodedArray::Make(10, run_ends,
values));
auto expected = ArrayFromJSON(arrow::Boolean(), "[true, null, null, null,
true,true,true,true,true,null]");
CheckScalarUnary("true_unless_null", z, expected);
}
```
