In A the only accidentals in this bar are two sharps: before G
at the beginning of the bar, and g in the R.H. The 
before the bottom note of the octave was added in all remaining sources. Besides this Chopin wrote into GC three more naturals, before the 1st semiquaver (b), and before the last octave (B1-B). GE supplemented the record of GC with a 
before b at the start of the 2nd half of the bar (this note is written in the sources on the lower staff). That was also added in FE2 (→FE3) and EE. The latter further added only both accidentals at the beginning of bar leaving the last octave without naturals.
