Hi,

I've just done a Mac OS X PPC build of the SVN trunk and am getting this
failure too.

nidesk046:~/scratch/upstream/scipy mark$ python
Python 2.4.1 (#2, Mar 31 2005, 00:05:10) 
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as N
>>> N.__version__
'1.0.dev3378'
>>> N.array([1000],dtype=N.float).dtype
dtype('float64')
>>> N.array([1000],dtype=N.longfloat).dtype
dtype('float128')
>>> N.test()
...snip...
FAIL: Ticket #112
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/numpy/core/tests/test_regression.py", line 220, in check_longfloat_repr
    assert(str(a)[1:9] == str(a[0])[:8])
AssertionError
>>> a = N.exp(N.array([1000],dtype=N.longfloat))
>>> str(a)
'[inf]'


Any ideas about this?

Mark
