Thank you for clarification.

There is yet another one. Could you please also comment on its severity?

Lot of similar following.

Obviously this does not currently effect any of the other regressions on 
msvc-6.5.

Will you mark them as expected failures, or shall I do it?

one final question though:

Given that we mark a lot of tests as unusable, how reliable is the
regression of the other libraries?

Thank you,
Roland
