Hi
> 2) if not, how shall I submit a bug-report?
I don't think it's a known issue and I would suggest submitting a PR anyway, it will take you only a couple of minutes:
http://gcc.gnu.org/bugzilla/
please add in CC: Johannes Singler <singler@ira.uka.de>, the main author of the code.
By the way, I see that this patch went in just before the release of 4.3.1:
http://gcc.gnu.org/ml/libstdc++/2008-06/msg00004.html
and I fear a regression... Do you have any data about 4.3.0? Or want to check what happens if you revert the above?
Many thanks in advance,
Paolo.
