It's the engraver causing the problem, more precisely the
stencil-setting. Not sure why, though.

You can do:

\version "2.18.2"
\language "english"


bar-highlight-engraver =
#(lambda (context)
  `((acknowledgers
     (bar-line-interface
         . ,(lambda (engraver grob source-engraver)
             (ly:grob-set-property! grob 'before-line-breaking
                (lambda (g)
                   (ly:grob-set-property! g 'stencil
                     (ly:stencil-in-color
                       (ly:bar-line::print g)
                       1 0 0 )))))))))


\layout {
  \context {
    \Staff
    \consists #bar-highlight-engraver
  }
}

\new Staff {
  \clef bass
  \time 4/4
  \key c \major

  \repeat unfold 5 { a,4 b, c d | }
  \bar ":|.|:"
  %\bar ".|:-||"
  \break
  \repeat volta 2 {
    \repeat unfold 5 { d c b, a, | }
  }
}

Cheers,
