What is broken is calculating eigenvalues of complex-valued sparse matrices and iterative solution of complex-valued linear equations. I.e., nothing obscure. A likely explanation is that win32 + Numpy 1.9 is a less common platform, and users whose code started failing just infrequently do not report bugs as easily... > The majority of f2py should still be working, numpys own f2py testsuite > passes on win32. Perhaps the arrays are aligned by chance? I don't think the test suite repeats the complex valued intent(inout) parameter test many times.

David's test case is this: n = 4 x = np.zeros(n * 3, dtype="D") _dummy.zfoo(x, n) where the argument is declared as "double complex, dimension(3*n), intent(inout)" in f2py. The ARPACK stuff in Scipy also does pretty much just this. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
