It's probably this issue:

        http://projects.scipy.org/numpy/ticket/1211

The most likely cause is that the linear algebra libraries
(ATLAS/BLAS/LAPACK) shipped with that version of 64-bit Opensuse are
somehow broken. At least on Mandriva it turned out that the problem did
not appear if ATLAS was not installed, and it also went away with a
newer version of LAPACK.

(special.hermite is pure-python code. The only part that can cause
problems is scipy.linalg.eig or numpy.linalg.eig, and, much less likely,
scipy.special.gamma. The former are thin wrappers around LAPACK
routines.)
