In the following example, the highest note is correctly printed in the first bar, but in the second bar the accidental is shifted to the left.

:::TeX
\version "2.12.1"

<<
  { gis''1 gis'' }
  \\
  { <fis' g'>1 <f' gis'> }
>>

Mark has done some extensive tests on http://lists.gnu.org/archive/html/bug-lilypond/2008-11/msg00039.html.

A related example from Mark:

"An accidental may move away from its note if there is
an interval of second nearby. The closer the second,
the further the accidental moves. This looks weird!"

:::TeX
\relative {
  <g' a gis'!> <a b gis'!> <b c gis'!> <c d gis!>
  <<
    { gis'! gis! gis! gis! }
    \\
    { <g, a> <a b> <b c> <c d> }
  >>
}

Han-Wen:
"Joe, maybe we should increase the slope for the accidental skylines?"

The behaviour for the first example is explained by the fact that we align accidentals belonging to the same octave. The second example is fixed in git.

Hmm. Looks a bit funny though; are we sure we want to keep this rule?

New comment from Mark:
Ted Ross (pp.130-135) demonstrates that the preference is overridden in the presence of a second. The preference to have the lower natural close to its note-head overrides the preference to align the octave. Even in the absence of a second, Ross gives cases where it makes more sense *not* to align the octaves.

More examples attached.

Also, the behaviour mentioned in comment #1 is not fixed.  Issue 2144 was opened to remember about it.
