Camm, thanks for the increasing number of bug reports ;-)

- please make sure to test with recent compiler versions (currently
  4.0.1-9).
- please check with optimization levels suggested by policy (-O2)
- please check using gcc-snapshot.

At least I cannot reproduce this with 4.0.1-9.

Thanks, Matthias

workaround, no feedback, non standard options, unreproducible, maybe I
should just close it ...

Version: 3.6.0-20.6

The atlas3 package has been removed from Debian testing, unstable and
experimental, so I am now closing the bugs that were still opened
against it.

For more information about this package's removal, read
http://bugs.debian.org/473440 . That bug might give the reasons why
this package was removed, and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.
