LilyPond forces 20 measures on one line so that the dot of the first note runs into the following note:

\relative c' {
  \override Score.SpacingSpanner #'packed-spacing = ##t
  \repeat unfold 20 { c2. \newSpacingSection e4 }
}

(not sure if this is how \newSpacingSection should be applied, though)

    Actually, looks like \newSpacingSection has nothing to do with this.

    Try the following code:

    \relative c' {
      \override Score.SpacingSpanner #'packed-spacing = ##t
      \repeat unfold  14 { c2. e8  e8 }
    }

    One more example:

    \relative c' {
      \override Score.SpacingSpanner #'packed-spacing = ##t
      \repeat unfold  10 {c4  c4. d4 e8 }
    }

    The two examples added by Alexander work perfectly fine with 2.19.83.
    The original example still shows the bug:

    \version "2.19.83"
\relative c' {
  \override Score.SpacingSpanner.packed-spacing = ##t
  \repeat unfold 20 { c2. \newSpacingSection e4 }
}

    (see original.png)

    But as this example shows, packed-spacing isn’t at the core of the problem, but any mid-bar use of \newSpacingSection will disable some collision control:

    \version "2.19.83"
\relative {
  \accidentalStyle forget
  <cis' eis gis cis>2  \newSpacingSection  q
  s4. g'8  \newSpacingSection  <c d f>2
}
