I can still reproduce this with current cvs snapshot.
I imported cvs sources into git and tried git-bisect.
git-bisect says the problem started with change #22557.

[refs/bisect/bad] [bisect] 22557: turn on multibyte option by default
[refs/bisect/good-b76d3fa3515823810784266bbf0c9cc1c58c504d] fix typos in 22556

Build script is attached.
