That might be so, but I can't verify that. :(

Unfortunately I forgot to note the exact svn revision at which the test failed,
and reverting the 174133 revision (backport to 4.3 documented in PR42775) from
revision 175148 and following the to-repeat description does not expose the
bug.

Hm, I see I mentioned 4.3.3 in this quite old report but as I can't repeat it
with a revision near ToT, I believe it's time to retire this PR and close it as
WORKSFORME rather than WONTFIX.
