Thank you.
Now there is only one "failure" in scipy.test() using FORTRAN LAPACK/BLAS.

 ======================================================================
FAIL: check_heev_complex (scipy.lib.lapack.test_lapack.test_flapack_complex)

Traceback (most recent call last):

Ran 1172 tests in 2.816s

FAILED (failures=1)
<unittest.TextTestRunner object at 0x412482ac>

Meanwhile, I have also test gcc3.3.4, gcc3.3.2 and gcc3.3.1 
(SuSE9.2/SuSE9.1 /SuSE9.0).
Unfortunately, I got the same segmentation faults as mentioned earlier 
when using ATLAS 3.6 / 3.7.8.
This fact is (at least from my point of
view) very unsatisfactory.

Any comment would be appreciated.
