Description Casey Dahlin 2009-04-06 14:37:10 UTC 
Description of problem:
Numeric.reshape raises ValueError exception when newshape has more than 1 dimension. This problem is observed only on x86_64 machines.

Version-Release number of selected component (if applicable):
python-2.4.3-24.el5
python-numeric-23.7-2.2.2

How reproducible:
Only reproducible on x86_64. 32-bit machines are correct.

Steps to Reproduce:
On a RHEL 5 x86_64 machine:
[root@dhcp6-118 ~]# python
Python 2.4.3 (#1, Sep 17 2008, 16:07:08)
[GCC 4.1.2 20071124 (Red Hat 4.1.2-41)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Numeric
>>> print Numeric.__version__
23.7
>>> a = Numeric.array([x for x in xrange(20)])
>>> Numeric.reshape(a, (4,5))
Traceback (most recent call last):
 File "<stdin>", line 1, in ?
ValueError: total size of new array must be unchanged
>>>

Expected results:
As seen on a 32 bit RHEL 5 machine :

>>> Numeric.reshape(a, (4,5))
array([[ 0,  1,  2,  3,  4],
      [ 5,  6,  7,  8,  9],
      [10, 11, 12, 13, 14],
      [15, 16, 17, 18, 19]])

Additional info:
Bug was fixed in Fedora in bug 192895, by rebasing to 24.2. Customer would prefer that solution for RHEL if possible. 24.2 was released in 2005.

Comment 4 Bob Arendt 2010-05-13 16:11:44 UTC 
Will python-numeric be updated in RHEL6 to the later version?  Or at least remove the buggy version?  Thanks.
Comment 6 RHEL Program Management 2010-08-09 19:12:49 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
