Hello, the following code crashes in the last line when using numpy 1.5.1 on Python 3.1 and 3.2, 32 and 64 bit, for Windows. It works with Python 2.x. Can anyone confirm the crash on other platforms? import numpy RECORD1 = [('i', 'i4')] RECORD2 = [('j', RECORD1, 2)] a = numpy.recarray((1,), RECORD2) a.data Christoph
