Seen on the AMD64 Mountain Lion Optimized [SB] 2.7 buildbot (http://buildbot.python.org/all/builders/AMD64%20Mountain%20Lion%20Optimized%20%5BSB%5D%202.7): test test_doctest crashed -- <type 'exceptions.AssertionError'>: filter ('backquote not supported', SyntaxWarning) did not catch any warning Traceback (most recent call last): File "./Lib/test/regrtest.py", line 896, in runtest_inner File "/Users/cpython/buildslave/optimized/2.7.snakebite-mountainlion-amd64-optimized/build/Lib/test/test_doctest.py", line 2684, in test_main test_support.run_doctest(test_doctest, verbosity=True) File "/Users/cpython/buildslave/optimized/2.7.snakebite-mountainlion-amd64-optimized/build/Lib/contextlib.py", line 24, in __exit__ self.gen.next() File "/Users/cpython/buildslave/optimized/2.7.snakebite-mountainlion-amd64-optimized/build/Lib/test/test_support.py", line 641, in _filterwarnings missing[0]) AssertionError: filter ('backquote not supported', SyntaxWarning) did not catch any warning The same failure is seen in test_syntax and test_zipimport_support. That buildbot builds the interpreter --with-pydebug but runs the test suite with -OO: ./python.exe -Wd -3 -E -tt -OO -R ./Lib/test/regrtest.py -uall -rwW I am able to reproduce the buildbot failures when run as above. Without "-OO", the tests no longer fail.

Without -3 option tests passed.

Python 2.7 is no longer supported.
