Thanks for testing the latest beta2 release.

This link has the following stacktrace:

/lib/libpython3.3m.so.1.0(PyMem_Free+0x1c)[0xbf044c]
/usr/lib/python3.3/site-packages/numpy/core/multiarray.cpython-33m.so(+0x4d52b)[0x42252b]
/usr/lib/python3.3/site-packages/numpy/core/multiarray.cpython-33m.so(+0xcb7c5)[0x4a07c5]
/usr/lib/python3.3/site-packages/numpy/core/multiarray.cpython-33m.so(+0xcbc5e)[0x4a0c5e]

Which indeed looks like in NumPy. Would you be able to obtain full stacktrace?

There has certainly been segfaults in Python 3.3 with NumPy, but we've
fixed all that we could reproduce. That doesn't mean there couldn't be
more. If you could nail it down a little bit more, that would be
great. I'll help once I can reproduce it somehow.
