I reproduced the bug in C++ and found about the same thing. (For anyone who is interested, checkout my repro branch https://github.com/zanmato1984/arrow/tree/fix-41813. Note you'll still need the data in the repro archive.) The bug seems to be that the group ids in the swiss table used by `GrouperFastImpl` are somehow wrong, causing the right rows obtained from it to be nonsense. Still digging. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
