At the beginning of the bar, Chopin entered into A a cautionary  to a. GE (→FE,EE,IE) added a  also to a2 in the R.H.
In the 2nd half of the bar the  to g is missing in A. The accidental was added in GE (→FE,EE,IE), yet it was erroneously placed only just before the last quaver.

In A the 2nd half of the bar is devoid of accidentals in the R.H. part. The inaccuracy, typical of this manuscript, was corrected in GE (→FE,EE,IE).

In A the flats lowering e to e on the penultimate quaver are missing. The accidentals were added in GE (→EE,FE,IE), which seems to be right due to the key of C minor, established already in bar 176. However, the chords in the three discussed bars are of a transitional nature (except the G chord at the beginning of each of them), hence this argument does not allow us to absolutely rule out e notes. However, the e notes in the topmost voice (present at the end of each of these bars, hence directly after the discussed chords) are another argument against e.

In A in bar 180 we can see a small cross (×) over the problematic note. It seems improbable that this mark, although written in ink, could have come from Chopin. It is probably an addition by someone who was going through the manuscript and had doubts about the pitch of this note. Was it the reviser of GE? If that were the case, it would be strange that he marked only this place, since the Sonata abounds in such issues (however, see the note on bar 255). Therefore, it could be a mark added by one of the later owners of the manuscript.
