Hi, I have this on my OSX 10.6 system and numpy 1.5.1 and current numpy head (30ee1d352):
$ python3.2 Python 3.2 (r32:88452, Feb 20 2011, 11:12:31) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import numpy as np >>> a = np.zeros((1,), dtype=[('f1', 'f')]) >>> a['f1'] = 1 >>> a['f2'] = 1 Segmentation fault All tests pass with np.test() Expected behavior with same code on python2.6: >>> a['f2'] = 1 Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: field named f2 not found.
