Re: [Numpy-discussion] storage for records

[Stefan v. d. W. <st...@su...>]

I am probably trying to do something silly, but still:

In [1]: import numpy as N

In [2]: N.__version__
Out[2]: '0.9.6.2127'

In [3]: P = N.array(N.zeros((2,2)), N.dtype((('f4',3), {'names': ['x','y','z'], 'formats': ['f4','f4','f4']})))
*** glibc detected *** malloc(): memory corruption: 0x0830bb48 ***
Aborted

Regards
Stéfan
