I've been using the new record arrays and lexsort from numpy quite a lot
lately. Very cool stuff.
Using the nightly egg for numpy from here (I believe it is up to date...):
http://code.enthought.com/enstaller/eggs/numpy-nightly-py2.4-win32.egg
I get segfaults when using lexsort on character arrays. A lot of my
columns in record arrays are string based, so sorting the arrays based
on these columns would be really handy.
Here is an example that crashes for me.
<http://code.enthought.com/enstaller/eggs/numpy-nightly-py2.4-win32.egg>C:\wrk\mt\trunk\src\lib\mt\statement\tests>python
Python 2.4.3 - Enthought Edition 1.0.0 (#69, Aug 2 2006, 12:09:59) [MSC
v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from numpy import lexsort
>>> lst = [1,2,3]
>>> lexsort((lst,))
array([0, 1, 2])
>>> lst = ['abc','cde','fgh']
>>> lexsort((lst,))
<seg-fault>
Do others see this?
