This fixes an out-of-bounds write that mimalloc caught during free(). ListArray::FromArrays does some sanitization, but had an off-by-N error: for a length N array, given N + 1 offsets, it correctly copied N validity bits from the offset array, but then tried to clear the N+2nd bit. Usually this would be fine anyways, given that there would be extra bits/bytes in validity buffer, but not always. -- This is an automated message from the Apache Git Service.
