Hello,
Thank you, that worked. It did see that fix, but I thought it was part
of version 0.6.0.
Now I have another problem, I get the following error:
======================================================================
FAIL: check_x_stride (scipy.linalg.tests.test_fblas.test_cgemv)

The weird thing is, the two arrays (x and y) are the same. Any thought,
someone?
