I cannot reproduce this segfault

>>> 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
>>> fblas.sger(1,[1,2],[3,4])
array([[ 3.,  4.],
        [ 6.,  8.]], dtype=float32)
