Great! I really appreciate! You're very helpful in catching this rare
bug. Alas, there is still nothing obvious at least to me, so I need
more time for any idea...

BTW, one little doubt: are you really sure vanilla 2.6.24 (without .6
etc.) gives the same? (There were some changes backported from 2.6.25
which I'd like to exclude.)
