Comment:

 Hi. I'm seeing both failures on 0.10.0.dev from github compiled under OS X
 Lion using [http://scipy.org/Installing_SciPy/Mac_OS_X#head-
 9ec15aabd402675e5139a8c9c727e6a23513d56a these] notes, with a slight
 different on the function which is failing on the
 test_iterative.test_convergence:

 {{{
 ======================================================================
 FAIL: test_iterative.test_convergence(<function bicg at 0x10122b230>,
 <nonsymposdef>)

 }}}

 I'm attaching the dump.npz.
