segfault on searchsorted of wrong dtype in structured array (Trac #2189)

[numpy-gitbot]

Original ticket http://projects.scipy.org/numpy/ticket/2189 on 2012-07-23 by trac user akhmerov, assigned to unknown.

numpy.searchsorted causes segfault when one searches in a structured array with a wrong dtype.

Bug is reproduced by: python -c "import numpy as np; a = np.array([('a', 1)], dtype='S1, int'); np.searchsorted(a, 1.2)"

This now gives:

(py27)ondrejatmention:hawk:~/repos/numpy/tools(fix369)$ python -c "import numpy as np; a = np.array([('a', 1)], dtype='S1, int'); np.searchsorted(a, 1.2)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/ondrej/repos/numpy/py27/lib/python2.7/site-packages/numpy/core/fromnumeric.py", line 814, in searchsorted
    return searchsorted(v, side, sorter)
TypeError: invalid type promotion

I am now working on a test and I'll submit a PR soon.
