I fear so - the
In [1]: from scipy.linalg import fblas
Importing io to scipy
Importing special to scipy
Importing utils to scipy
Importing interpolate to scipy
Importing optimize to scipy
Importing linalg to scipy

In [2]: fblas.sger(1,[1,2],[3,4])
Segmentation fault

on the opteron persists.
(If you would like give me some guidance what to do next
to track this down, I am all ears).

On my PIV:
scipy.test(10,10) gives
[...]
check_zero (scipy.linalg.matfuncs.test_matfuncs.test_expm) ... ERROR
check_nils (scipy.linalg.matfuncs.test_matfuncs.test_logm) ... ERROR
check_defective1 (scipy.linalg.matfuncs.test_matfuncs.test_signm) ...
ERROR
check_defective2 (scipy.linalg.matfuncs.test_matfuncs.test_signm)zsh: 3052
floating point exception

(Revisions 1315 and 1345 for newcore and newscipy on both machines)

Best,

Arnd
