 If I run scipy.test(1,10) several times I get a second failure (besides
the persistent one
FAIL: check_random_complex_overdet
(scipy.linalg.tests.test_basic.test_lstsq)

======================================================================
FAIL: check_y_stride_transpose (scipy.lib.blas.tests.test_fblas.test_cgemv)

Can someone reproduce this sporadic failure ?
