Hrrmph. Looks like the pathname rewrite (stripping leading '/')
is getting done too late, so that the wrong filenames are
being compared.
Please check that the following does work (without the leading '/'):
tar -cf foo.tar usr/dir_a/dir_b
tar -uvf foo.tar usr/dir_a/dir_b
Assuming that works correctly, I know where the mistake is;
I'll have a tentative patch for you to try in a couple of hours.
