Comment(by claumann):

 Standard structured arrays segfault on Mac OSX with Enthought's python
 2.7.2, but github numpy 2.0.0.dev-26aa3cf.

 Using Fonnesbeck's current superpack (Apple Python 2.7.1 from Lion, numpy
 1.7.0.dev-3503cf), the same code raises an type promotion error. Don't
 know if this is related to enthought or if the github master doesn't have
 the same type checking that 1.7.0.dev seems to have..

 Python 2.7.2 |EPD 7.1-1 (64-bit)| (default, Jul  3 2011, 15:56:02)

 In [3]: a = np.array([(2,2),(2,2)], dtype)

 In [4]: np.searchsorted(a, r_[1])
 Segmentation fault: 11
