I was making some simple changes to fileobject.c yesterday (checking file()
mode strings for validity) and started having test failures.  After lots of
head scratching and changes to my code I concluded it couldn't be my code
and finally just ripped out the changes and ran with a fresh CVS checkout.
Sure enough, I got the same problem.  On Mac OS X I get this output (debug
build):

    ...
    test_sys
    test_tarfile
    test_tcl
    test_tempfile
    *** malloc[24360]: error for object 0x680b408: Pointer being reallocated was not allocated
    [5939 refs]
    test test_tempfile failed -- Traceback (most recent call last):
      File "/Users/skip/tmp/python/dist/src/Lib/test/test_tempfile.py", line 155, in test_wanted_dirs
	os.environ[envname] = os.path.abspath(envname)
      File "/Users/skip/tmp/python/dist/src/Lib/os.py", line 445, in __setitem__
	putenv(key, item)
    OSError: (0, 'Error')

    test_textwrap
    test_thread
    test_threaded_import
    test_threadedtempfile
    test_threading
    test_time
    make: *** [test] Bus error

This stuff passes with no complaint on Linux (Mandrake 8.1-ish) but I'm
having other problems there.  Tests involving bsddb fail (I'm building with
Berkeley DB 3.3 - is that too old now?) with something like this:

    test_anydbm
    U‰åSƒìcèíÂ
    make: *** [quicktest] Segmentation fault

On both Mac OS X and Linux (Mandrake 8.1-ish) test_site fails with:

    test test_site failed -- Traceback (most recent call last):
      File "/home/skip/tmp/python/dist/src/Lib/test/test_site.py", line 150, in test_sitepackages
	self.fail("'site-packages' directory missing'")
    AssertionError: 'site-packages' directory missing'

This seems like a problem with the test itself.  It should be okay to run
the tests in the build directory without a site-packages directory.

I'm doing a little further investigation into the malloc problem on Mac OS X
using the debug stuff available in its malloc(3) implementation.
