Sorry, Pearu, but I still get one on the opteron:

  from scipy.linalg import fblas
  fblas.sger(1,[1,2],[3,4])

segfaults ( check_ger from test_blas.py).

This is with
In [1]: import scipy
In [2]: scipy.base.__version__
Out[2]: '0.4.3.1300'
(and new scipy At revision 1336).

Additional remark:
  After commenting out all tests in check_ger()
  all tests run through.
  Now, removing the commmented out part
  and re-running the test in a new session
  gives no segfault - very weird!
  Anway, the above two lines do reproduce the segfault
  systematically.

Best, Arnd
