In A Chopin omitted many accidentals, which, due to the context, does not cast doubt on the pitch of the respective notes. We are dealing with the sharps to g
3 and c4 in bar 126 and to c3, g2, f2 and g1 (L.H.) in bar 127, as well as the naturals to e3 (the 2nd quaver) and a2 in bar 127. In GE (→EE,IE) all the missing accidentals were added except the 
to g2 in bar 127, which was added only in FE.
Moreover, all editions feature a 
to e3 on the 4th quaver in bar 127, unnecessary after adding a respective accidental 2 notes earlier.
