--- Comment #59 from b. <newbie-02 at gmx.de> ---
hello @Dante, 

previous comment was the 'last needed patch'? 

testing with 7.2 ver. from 2021-05-11 ~04h, i see: 

your sample sheet working, 

mine 'kahan_sum with different versions' still failing (12,475), 

note that we have different operand sequences, you: 
1e15, 0.1, -1e15, 0.1, 1e15, 0.1, -1e15, 0.1, ... while i tested with: 
1e15, 0.1, -1e15, 1e15, 0.1, -1e15, ... 

tested my sheet fine with your data, 
your sheet failing with my data, 

pls. recheck if the mistake is on my side,
