Thanks Mark, super job!
Unfortunately this means, unless there is some #ifdefine in ATLAS which
branches as a function of the compiler, that this is a compiler bug.
Would I be asking too much, if I'd ask you to check with the latest gcc
(version 4.1.3 20070831 (prerelease) (Ubuntu 4.1.2-16ubuntu1
-20 is OK with gcc3.4 as well.

OK, so after a bit of a battle (had to do a manual build), compiling -19
using gcc3.4.6/dapper, the problem is _absent_.

If you can confirm that the problem is solved with 3.6.0-13 than it is not a
bug introduced upstream. Both 3.6.0-13 and 3.6.0-20 should be using the same
upstream version (3.6.0).

Also, there is a new scipy release (5.2.1). We looked at it for
inclusion in Gutsy and the changes are (despite the version number)
invasive and wide ranging so we decided to pass. If 5.2.1 from upstream
does not demonstrate this problem, then maybe we could work together to
pull out a patch from
Right now, I think the best would be to send the test script and matrix
upstream, to see if they can reproduce it.
This could give us some clues on where to start.

If you open a ticket, please let us know the number so that we can track
the discussion.

Also the fact that the error is seen on the dapper/pentium argues
against a hardware problem.

Cesare,
Thanks for your quick, and apologies for my slow, reply.

By giving a quick look at the runtime libraries, I don't think the
problem is related to these:
dapper:
atlas3-base (3.6.0-20)
lapack3 (3.0.2531a-6ubuntu2)
refblas3 (1.2-8ubuntu1)
edgy:
atlas3-base (3.6.0-20.2)
lapack3 (3.0.2531a-6ubuntu2)
refblas3 (1.2-8ubuntu1)
the only differences bet
PS it's not the value of tol that's causing the problem.
Now I've seen the "Attachment" button, SciTest.tgz contains the test
script and matrix.
