New submission from Ned Deily:

== CPython 3.3.0b1 (default:efb30bdcfa1e, Aug 8 2012, 15:43:49) [GCC 4.0.1 (Apple Inc. build 5493)]
==   Darwin-8.11.0-Power_Macintosh-powerpc-32bit big-endian
==   /private/tmp/test_python_13864
Testing with flags: sys.flags(debug=0, inspect=0, interactive=0, optimize=0, dont_write_bytecode=0, no_user_site=0, no_site=0, ignore_environment=0, verbose=0, bytes_warning=0, quiet=0, hash_randomization=1)

FAIL: testChainingDescriptors (test.test_exceptions.ExceptionTests)
----------------------------------------------------------------------
Traceback (most recent call last):

    self.assertTrue(e.__suppress_context__)
AssertionError: False is not true

Other similar test failures include multiple test cases in test_ipaddress, test_raise, and test_traceback, for example:

ValueError: Only hex digits permitted in 'axy'

During handling of the above exception, another exception occurred:

During handling of the above exception, another exception occurred:

The same universal build runs without error on an Intel Mac with the same os version.  The ppc failures are seen on both PPC OS X 10.5 and 10.4 systems.
