Look at the following examples
(1)
%\unfoldRepeats
\new Staff {
 \time 4/4
 \clef "bass"
 c'2 c'
 \repeat volta 2 { c' c' | \clef "treble" c'  c' \clef "bass" }
  c' c'
}

Imho, all's correct, even if you uncomment unfoldRepeats

(2)
%\unfoldRepeats
\new Staff {
 \time 4/4
 \clef "treble"
 c'2 c'
 \repeat volta 2 {
  %\clef treble
  c' c' |  c'  c'
  \clef "bass"
 }
  c' c'
}

Here the bass-clef at end-repeat is misleading.
Uncommenting unfoldRepeats will lead to likely undesired results
(which can be fixed by uncommenting the treble-clef at start-repeat)


Though, how should LilyPond behave differently?
The clef at end-repeat can't know which one is valid at start-repeat.

So I tend to "no bug" or rather "won't fix".
I don't see a possibility to make it work without adding a wagonload of code.
Likely in C++, so I'm out anyway.

Instead you can add the proper clef at start-repeat (it will not be
printed unless forced), to fix repeatUnfold, and use something at the
lines of the override Mark provided already.

Cheers,
