Segfault 11 with pandas with Python v2.7.6 RC1 on Mac OS X 10.9

Question

In [1]: import json In [2]: path = 'ch02/usagov_bitly_data2012-03-16-1331923249.txt' In [3]: from pandas import DataFrame, Series; In [4]: records = [json.loads(line) for line in open(path)] In [5]: frame = DataFrame(records) In [6]: frame['tz'][:10] Segmentation fault: 11 

Any access to the frame leads to segfault. I have already upgraded to Python 2.7.6 RC1. Also happened in 2.7.5, also happens outside ipython. What should I do?

This seems to be a bug in Numpy that has been fixed recently. See https://github.com/numpy/numpy/issues/3962
