Merged revisions 65339-65340,65342 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk ........ r65339 | amaury.forgeotdarc | 2008-07-31 23:28:03 +0200 (jeu., 31 juil. 2008) | 5 lines #3479: unichr(2**32) used to return u'\x00'. The argument was fetched in a long, but PyUnicode_FromOrdinal takes an int. (why doesn't gcc issue a truncation warning in this case?) ........ r65340 | amaury.forgeotdarc | 2008-07-31 23:35:03 +0200 (jeu., 31 juil. 2008) | 2 lines Remove a dummy test that was checked in by mistake ........ r65342 | amaury.forgeotdarc | 2008-08-01 01:39:05 +0200 (ven., 01 août 2008) | 8 lines Correct a crash when two successive unicode allocations fail with a MemoryError: the freelist contained half-initialized objects with freed pointers. The comment /* XXX UNREF/NEWREF interface should be more symmetrical */ was copied from tupleobject.c, and appears in some other places. I sign the petition. ........
