But it doesn't need to be polyphonic nor
does it need \addlyrics to go wrong.  Nor
it is anything to do with the implicit
creation of contexts.  Try:

\version "2.13.3"
\relative c' {
 \new Staff {
   <<
     \new Voice = "A" { a4 a a a | a }
     \new Lyrics \lyricsto "A" \lyricmode {
       a a a a a }
   >>
   \context Voice = "A" { d d d | f f f f }
 }
}

It seems more a problem of timing synchonisation
between lyricmode and notemode.  In lyricmode it
seems the last syllable extends to the end of the
second bar, causing the following notes to squash
up until the notemode timing catches up.

The ordering is unusual, but it does seem like a
bug.
