The deletions visible in A at the beginning of the bar reveal that Chopin initially wrote d
1 as the bottom note of the 1st chord, accompanied by F (con 8) as the L.H. octave. Therefore, the 
to the next d1 crotchet was most probably meant to cancel the alteration and not to perform the role of a cautionary accidental following d
in the preceding bar.
