@emkornfield the read crashes inside of Def Levels to Bitmap because the leaf array has no elements despite there being 1 record because it's an empty list. The initialization of the bitmap writer attempts to grab a reference to the first byte of the bitmap, but because `lenBound` was 0, we resized the buffer to 0 bytes, so it tries to read byte 0 of an empty slice. It's definitely possible the C++ impl has this same issue, i haven't checked. -- This is an automated message from the Apache Git Service.
